151 It takes a "remove" option to remove all the staged
152 files.
153
154vms_eco_level.h This sets the ECO level for the PCSI kit name.
155
156
157How to Build:
158
159The GNV based build and the DCL based build procedures are not compatible
160and you must make sure that none of the build files are present before
161running a different type of build. Use the "REALCLEAN" option for
162BUILD_VMS.COM and the "REALCLEAN" option for clean_gnv_curl.com.
163
164The (brute-force) DCL based builder is [.packages.vms]build_vms.com.
165Comments in this procedure describe various optional parameters which
166enable or disable optional program features, or which control the build
167in other ways. Product files (.EXE, .H, .LIS, .MAP, .OBJ, .OLB, ...)
168should be produced in an architecture-specific subdirectory under this
169directory ([.ALPHA], [.IA64], [.VAX]).
170
171The file curl_gnv_build_steps.txt contains information on building using
172the GNV tool kit, building a shared libcurl, and producing a PCSI kit for
173distribution. The curl_gnv_build_steps.text is included in the release
174notes file of the PCSI kit.
175
176The building with 64 bit pointers does not currently work.
177
178The build procedure will detect if HP OpenSSL, LDAP, and Kerberos are
179installed and default to building with them.
180
181The build procedure will also detect if a compatible ZLIB shared image
182is installed from a PCSI kit and default to using it.
183
184 Example build commands:
185
186 @ [.packages.vms]build_vms.com CLEAN
187 @ [.packages.vms]build_vms.com LARGE LDAP
188 submit /noprint [.packages.vms]build_vms.com /param = (LARGE, LDAP)
189
190The build_vms.com procedure does not build the shared image file or the PCSI
191kit. If you have built a curl with ZLIB and HPSSL support as well as if
192LDAP and Kerberos installed, you can use the GNV_LINK_CURL.COM file.
193
194The GNV_LINK_CURL.COM contains information on how to link and run with a newer
195version of HP SSL than what may be install on an Alpha or IA64 based system.
196
197To build the PCSI kit, follow the instructions in the file
198curl_gnv_build_steps.txt.
199
200Other Notes:
201
202This release fixes known bugs #22, and #57 in the [curl.docs]known_bugs.
203file.
204
205The libcurl formdata.c module and Curl tools post form now have some
206understanding of VMS file types. Files will be posted in STREAM_LF format.
207
208The Curl tool now has some understanding of VMS file types and will upload the
209files in STREAM_LF format.
210
211When CURL is uploading a VARIABLE format VMS file, it is less efficient as in
212order to get the file size, it will first read the entire file once, and then
213read the file again for the actual upload.
214
215The Curl tool will now always download files into STREAM_LF format. Even if a
216file by that name with a different format already exists. This is needed to
217allow interrupted downloads to be continued.
218
219
220The libcurl file module still does not understand VMS file types and requires
221the input files to be in STREAM_LF to work property.
222
223The test suites are not supported as of 7.11.0.
224
225The curlmsg.sdl and curlmsg.h files are generated from curlmsg.msg.
226This is not done automatically, since the .MSG file is a hand edit
227of the relevant stuff from the curl.h file. If you want to do this
228yourself you'll need the SDL package from the freeware collection.
