octave-devel configure failure: to build Octave, you must have the PCRE library and header files installed

[Schamschula (Marius Schamschula)]

While updating octave-devel to version 3.6.4_7 +atlas +gcc48 darwin_10, I found a configuration issue:

:info:configure checking libqhull/libqhull.h usability... no

Looks like some CPPFLAGS are not being set, as both qhull and pcre headers can't be found.

As I had 3.6.4_6 +atlas +gcc47 darwin_10, working, but I followed the troubleshooting advice and removed it to re-attempt installing the current version. Rebuilding it using the old Portfile...

Please attach the main.log file.

[ryandesign (Ryan Carsten Schmidt)]

And let us know your version of Xcode please.

[Schamschula (Marius Schamschula)]

I'm using Xcode 4.2.

[michaelld (Michael Dickens)]

What does "port installed pcre" return?

[michaelld (Michael Dickens)]

Also, what do the following return for you:

gcc -v
cd `port dir qt4-mac`/files/cpath
/usr/bin/gcc -nostdinc -c cpath_test.c
CPATH=. /usr/bin/gcc -nostdinc -c cpath_test.c

Note: marius$ sudo CPATH=. /usr/bin/gcc -nostdinc -c cpath_test.c worked as expected.

[Schamschula (Marius Schamschula)]

marius$ port installed pcre The following ports are currently installed:

pcre @7.9_0 pcre @8.10_0 pcre @8.12_0 pcre @8.12_1 pcre @8.33_0 (active)

[michaelld (Michael Dickens)]

Thanks. The issue has something to do with permissions of your computer's filesystem. Can you run Disk Utility.app and have it repair disk permissions, then try

CPATH=. /usr/bin/gcc -v -nostdinc -c cpath_test.c

to see if it now works? If not, post the results here, surrounded by three { }; that's how I get the special box just above reading "CPATH ...".

I ran Repair Permissions on the boot HD.

However,

CPATH=. /usr/bin/gcc -v -nostdinc -c cpath_test.c

still fails.

Note when I do a ls -l on the enclosing directory for cpath I get

drwxr-xr-x  6 root  admin    204 Aug 26 12:52 cpath

Thus, no surprise why the .o file can't be written.

[michaelld (Michael Dickens)]

OK; try this:

cd ~/Desktop
cp -rp `port dir qt4-mac`/files/cpath_test
cd cpath_test
CPATH=. /usr/bin/gcc -v -nostdinc -c cpath_test.c

and see if that works. Permissions should be OK for this test, at least in your local directory; I think the permission issue is with /var/.....

Works just fine.

I'm assuming you meant /opt/local/var. Listing the enclosing directory:

Hmm .. interesting; CPATH is working, so I would expect octave's configure script to pick up the headers and such for pcre and qhull. I was not referring to /opt/local/var, but thanks. Can you attach the file "port dir octave-devel/work/octave-3.6.4/config.log"?

I get

Sorry, bad wiki formatting. I meant: "`port dir octave-devel`/work/octave-3.6.4/config.log" if you copy the text from the wiki.

Never mind. I found it manually.

OK; next up:

cd ~/Desktop
cp -rp `port dir qt4-mac`/files/cpath cpath_test_2
cd cpath_test_2
CPATH=. /usr/bin/clang -v -nostdinc -c cpath_test.c

and see if that works.

Excellent! I'll create a compiler blacklist for this port, since it relies on CPATH functionality which is clearly not present in the version of CLANG in Xcode 4.2. Back shortly.

[michaelld (Michael Dickens)]

Fixed in r110134. You'll want to do

sudo port selfupdate

before trying again.

Works for me.

Thanks!

Great! Thanks for the feedback.
