17 Currently building Curl using GNV takes longer than building Curl via DCL.
18 The GNV procedure actually uses the same configure and makefiles that
21 Building CURL on OpenVMS using GNV requires GNV V2.1-2 or the updated
22 images that are available via anonymous FTP at encompasserve.org in the gnv
23 directory. It also requires the GNV Bash 4.2.45 kit as an update from the
24 same location or from the sourceforge.net GNV project.
26 The HP C 7.x compiler was used for building the GNV version.
28 The source kits are provided in backup savesets inside of the PCSI install kit.
30 Backup save sets are currently the only distribution medium that I can be
31 sure is installed on a target VMS system that will correctly unpack files
32 with extended character sets in them. You may need to adjust the ownership
33 of the restored files, since /Interchange/noconvert was not available at the
34 time that this document was written.
36 [gnv.common_src]curl_*_original_src.bck is the original source of the curl kit
37 as provided by the curl project. [gnv.vms_src]curl-*_vms_src.bck, if present,
38 has the OpenVMS specific files that are used for building that are not yet in
39 the curl source kits for that release distributed http://curl.haxx.se
41 These backup savesets should be restored to different directory trees on
42 an ODS-5 volume(s) which are referenced by concealed rooted logical names.
44 SRC_ROOT: is for the source files common to all platforms.
45 VMS_ROOT: is for the source files that are specific to OpenVMS.
46 Note, you should create the VMS_ROOT: directory tree even if it is
47 initially empty. This is where you should put edits if you are
49 LCL_ROOT: is manually created to have the same base and sub-directories as
50 SRC_ROOT: and VMS_ROOT:
52 The logical name REF_ROOT: may be defined to be a search list for
55 The logical name PRJ_ROOT: is defined to be a search list for
56 LCL_ROOT:,VMS_ROOT:,SRC_ROOT:
58 For the make install process to work, it must have write access to the
59 directories referenced by the GNU: logical name.
61 In future releases of GNV, and with GNV Bash 4.2.45 installed, this name
64 As directly updating those directories would probably be disruptive to other
65 users of the system and require elevated privilege, this can be handled by
66 creating a separate directory tree to install into which can be referenced
67 by the concealed rooted logical name new_gnu:. A concealed logical name of
68 OLD_GNU: can be set up to reference the real GNV directory tree.
70 Then a local copy of the GNU/GNV$GNU logical names can be set up as a search
71 list such as NEW_GNU:,OLD_GNU:
73 The directory NEW_GNU:[usr] should be created. The make install phase should
74 create all the other directories.
76 The make install process may abort if curl is already because it can not
77 uninstall the older version of curl because it does not have permission.
79 The file stage_curl_install.com is used set up a new_gnu: directory tree
80 for testing. The PCSI kitting procedure uses these files as input.
82 These files do not create the directories in the VMS_ROOT and LCL_ROOT
83 directory trees. You can create them with commands similar to:
85 $ create/dir lcl_root:[curl]/prot=w:re
86 $ copy src_root:[curl...]*.dir -
87 lcl_root:[curl...]/prot=(o:rwed,w:re)
88 $ create/dir vms_root:[curl]/prot=w:re
89 $ copy src_root:[curl...]*.dir -
90 vms_root:[curl...]/prot=(o:rwed,w:re)
92 One of the ways with to protect the source from being modified is to have
93 the directories under src_root: owned by a user or resource where the build
94 username only has read access to it.
99 GNV currently has a bug where configure scripts take a long time to run.
100 Some of the configure steps take a while to complete, and on a 600 Mhz
101 DS10 with IDE disks, taking an hour to run the CURL configure is normal.
102 The bug appears to be in the SED for GNV 2.1.3 and GNV 3.0.1 where it
103 is taking far longer than it should to do I/O. In addition, there are
104 reports that the SED in GNV 3.0.1 is broken so the SED from GNV 2.1.3
105 should be used instead.
107 The following messages can be ignored and may get fixed in a future version
108 of GNV. The GNV$*.OPT files are used to find the libraries as many have
109 different names on VMS than on Unix. The Bash environment variable
110 GNV_CC_QUALIFIERS can override all other settings for the C Compiler.

121 With these search lists set up and the properly, curl can be built by
122 setting your default to PRJ_ROOT:[curl.packages.vms] where the * is
123 replaced by the actual version of curl, and then issuing the command:
125 $ @build_gnv_curl.com.
127 This command procedure does the following:
129 $ @setup_gnv_curl_build.com
131 $ bash gnv_curl_configure.sh
133 $ @clean_gnv_curl.com
135 $ bash make_gnv_curl_install.sh
139 $ @stage_curl_install.com
141 $ purge new_gnu:[*...]/log
143 To clean up after a build to start over, the following commands are used:
150 Then run the @clean_gnv_curl.com. Use the parameter "realclean" if you are
151 going to run the setup_gnv_curl_build.com and configure script again.
153 $ @clean_gnv_curl.com realclean
155 If new public symbols have been added, adjust the file gnv_libcurl_symbols.opt
156 to have the new symbols. If the symbols are longer than 32 characters,
157 then they will need to have the original be exact case CRC shortened and
158 an alias in upper case with CRC shortened, in addition to having an exact
159 case truncated alias and an uppercase truncated alias.
161 The *.EXE files are not moved to the new_gnu: directory.
163 After you are satisfied with the results of your build, you can move the
164 files from new_gnu: to old_gnu: at your convenience.
166 Building a PCSI kit for an archictecture takes the following steps after
167 making sure that you have a working build environment.
169 Note that it requires manually creating two logical names as described
170 below. It is intentional that they be manually set. This is for
171 branding the PCSI kit based on who is making the kit.
173 1. Make sure that you have a staging directory that can be referenced
174 by the path STAGE_ROOT:[KIT]
176 2. Edit the file curl_release_note_start.txt or other text files to
179 3. Define the logical name GNV_PCSI_PRODUCER to indicate who is making
180 the distribution. For making updates to an existing open source
181 kit you may need to keep the producer the same.
183 4. Define the logical name GNV_PCSI_PRODUCER_FULL_NAME to be your full
184 name or full name of your company.
186 5. If you are producing an update kit, then update the file
187 vms_eco_level.h by changing the value for the VMS_ECO_LEVEL macro.
188 This file is currently only used in building the PCSI kit.
190 6. Edit the file PCSI_GNV_CURL_FILE_LIST.TXT if there are new files added
191 to the kit. These files should all be ODS-2 legal filenames and
194 A limitation of the PCSI kitting procedure is that when selecting files,
195 it tends to ignore the directory structure and assumes that all files
196 with the same name are the same file, so every file placed in the kit
197 must have a unique name. Then a procedure needs to be added to the kit
198 to create an alias link on install and remove the link on remove.
200 Since at this time curl does not need this alias procedure, the steps
201 to automatically build it are not included here.
203 While newer versions of PCSI can support ODS-5 filenames, not all verions
204 of PCSI on systems that have ODS-5 filenames do. So as a post install
205 step, the PCSI kit built by these steps does a rename to the correct
206 case as a post install step.
208 7. Edit the build_curl_pcsi_desc.com and build_curl_pcsi_text.com if you
209 have changed the version of ZLIB that curl is built against.
211 8. Prepare to backup the files for building the kit.
213 Note that if src_root: or vms_root: are NFS mounted disks, the
214 step of backing up the source files will probably hang or fail.
216 You need to copy the source files to VMS mounted disks and create
217 logical names SRC_ROOT1 and VMS_ROOT1 to work around this to to
218 reference local disks. Make sure src_root1:[000000] and
219 vms_root1:[000000] exist and can be written to.
221 The command procedure compare_curl_source can be used to check
222 those directories and keep them up to date.
224 @compare_curl_source.com SRCBCK UPDATE
226 This compares the reference project source with the backup
227 staging directory for it and updates with any changes.
229 @compare_curl_source.com VMSBCK UPDATE
231 This compares the VMS specific source with the backup
232 staging directory for it and updates with any changes.
234 Leave off "UPDATE" to just check without doing any changes.
236 If you are not using NFS mounted disks and do not want to have a
237 separate directory for staging the sources for backup make sure
238 that src_root1: and vms_root1: do not exist.
240 9. Build the PCSI kit with @pcsi_product_gnv_curl.com
242 The following message is normal:
243 %PCSI-I-CANNOTVAL, cannot validate
244 EAGLE$DQA0:[stage_root.][kit]VMSPORTS-AXPVMS-CURL-V0731-0-1.PCSI;1
245 -PCSI-I-NOTSIGNED, product kit is not signed and therefore has
248 This will result in an uncompressed kit for the target platform.
249 On Alpha and Integrity, the pcsi_product_gnv_curl.com can be used with
250 the "COMPRESSED" parameter to build both a compressed and uncompressed
