Bug in configure script found (was xercesc requirements)

[realflash]

I have xercesc-2.6.0 installed at /usr/local/xerces-c, but running the configure script with

Code: [Select]

./configure --with-libxerces-c=/usr/local/xercesc
still results in the config script saying that it isn't installed. Can anyone hint on what further tests I can do to see what's wrong? I have put some debug code and can see that the param is getting into the script OK. Is it a binary release downloaded from xml.apache.org OK? The name libxerces-c seems a little misleading as xercesc is not referred to as this on xml.apache.org.

Any help would be greatly appreciated. Trying to test the latest CVS code.

I have added some more debug code, which shows that at the time of the g++ command being run, the working directory is /home/gibbsi/software/glest/glest/mk/linux. Which (I'm guessing) is where conftest.cc is created, so it's not likely to find xercesc under there, is it? Is there perhaps an include missing from this g++ command that gets run?

From config.log:

Code: [Select]

OK, I have cracked this now. It's due to a typo in the configure script. The test command is indeed wrong:

Code: [Select]

configure:4551: g++ -o conftest -I-c/include conftest.cc -L-c/lib -lxerces-c -lpthread >&5
should be

Code: [Select]

configure:4551: g++ -o conftest -I/usr/local/xercesc/include conftest.cc -L/usr/local/xercesc/lib -lxerces-c -lpthread >&5
where configure was run as

Code: [Select]

./configure --with-libxerces-c=/usr/local/xerces
On lines 4525 to 4529 of the configure script, a hyphen is used instead of an underscore:

Code: [Select]

CFLAGS="-I$with_libxerces-c/include $CFLAGS"
CPPFLAGS="-I$with_libxerces-c/include $CPPFLAGS"
LIBS="-L$with_libxerces-c/lib $LIBS"
RESCFLAGS="-I$with_libxerces-c/include $RESCFLAGS"
RESLIBS="-L$with_libxerces-c/lib $RESLIBS"
the var delcared eariler for the passed value of --with-libxerces-c is $with_libxerces_c. As a result, g++ gets called as

Code: [Select]

configure:4551: g++ -o conftest -I$with_libxerces-c/include conftest.cc -L$with_libxerces-c/lib -lxerces-c -lpthread >&5
where $with_libxerces is undefined, resulting in the duff command at the top. To temporarily resolve this issue and make configure work, download
this patch and apply it to configure:

Code: [Select]

patch configure < xercesc-configure.patch

This is only a temporary solution as if autogen.sh gets run configure will be rewritten.

fixed in cvs now.
