Re: octave-config-h?

I'm using an updated Fedora XFCE distro if it matters.

tl;dr : try bootstrap with the --gnulib-srcdir=<directory where gnulib-tool resides>

for me gnulib-tool lives in /usr/bin

I had a similar problem with a missing octave-config.h file the last couple days. The first time I hg cloned the dev code I tried to do the autoconf ./configure make like I normally do. I have a lot of flags for configure but I don't think they're relevant as they have remained pretty constant. I encountered errors and noticed an executable called bootstrap in my folder so I ran it with no flags just to see what would happen. It told me at the end that I could now run ./configure so I did it with all my flags and was able to run make without problem.

For some reason I decided I wanted to start over and tried to build in a separate directory. rm -rf ed the whole folder and did the hg clone again but I ran ./bootstrap without flags and ./configure like I always do excepted I added --prefix and --exec-prefix pointing to two empty directories in my home folder. I ran make and got the missing octave-config.h message. I tried to ./configure using my standard flags but it didn't help. I deleted the folder and recloned it and it didn't help. I reinstalled my OS and installed all the dependencies and it didn't help. I went to sleep.

Then yesterday I downloaded the source from the hg site as a *.tar.gz file. I uncompressed it and tried to run ./bootstrap with no flags. It complained that if I were going to run it without the git option to download gnulib then I had to specify my local copy of gnulib using the --gnulib-srcdir flag. I didn't specify no-git or whatever the flag was and I was puzzled by I went ahead and tracked down my local copy of gnulib and ran ./bootstrap --gnulib-srcdir=/usr/bin then configure with my regular flags. I ran make and it compiled. So I recloned the hg site and tried the same thing. It worked. I don't know how much of this was because of a new version of the source coming out or if me not specifying the gnulib-srcdir was the problem all along.

Either way my script for building from hg and building from *.tar.gz source are included. clonecompile.txt downloades from the hg site and builds. untarcompile decompresses it from a *.tar.gz file and builds. sourcescript.txt calls clone compile and backgrounds it then runs untar compile so I can download the hg version while compiling the *.tar.gz version. installlist.txt is a list of all the calls to my package manager that I've made. A lot of it is unnecessary for just building octave but it gives a complete picture of how my system is set up. The builds using this script pass the make check with all passes or XFails. JIT doesn't work because I haven't figured out how to make the the program compile against the old llvm without breaking the new version.

John,

Did the new octave-config.h not get pushed, or is it not ready yet?

I should have spent more time reviewing the recent changesets. Im able to use the new-file, mk-octave-config-h.sh, to generate octave-config.h.

./build-aux/mk-octave-config-h.sh config.h > octave-config.h

It looks to me like this should happen automatically

$ fgrep -in octave-config.h Makefile.am
148: octave-config.h \
175:octinclude_HEADERS += octave-config.h oct-conf-post.h
191:octave-config.h: config.h build-aux/mk-octave-config-h.sh

Expanding the relevant lines …

191 octave-config.h: config.h build-aux/mk-octave-config-h.sh
192 $(AM_V_GEN)$(top_srcdir)/build-aux/mk-octave-config-h.sh $< > address@hidden && \
193 mv address@hidden $@

Unfortunately, the build process doesn’t generate octave-config.h for me. I’m trying to build on Mac OS X and am using Fink for dependencies (anyone else?).

Perhaps there is a dependency requirement I’m lacking (maybe my version is too old?). Rather than dumping everything into email, I’ll wait for feedback.

It should happen automatically after this change:

http://hg.savannah.gnu.org/hgweb/octave/rev/5ddc9b61a0c4

Is octave-config.h listed in BUILT_SOURCES in your Makefile?
