Hi, testing the last svn version of geos. When try the "make check" I see this error:
I work on a RedHat ES6 - 64 bit.

I'm not sure to execute well your prescriptions.
I try:
gdb --args ./XMLTester -v --test-valid-output ./tests/testLeaksBig.xml .....
after execution it enter in gdb . I type bt, but it report: 'no stack'
To give more information, I report also the last part of messages from console..

Hi, I have obtain some result from gdb.
after an execution it report this I'm not sure if it is really useful :)

Oops, XMLTester is a libtool script, you'll need:
libtool --mode=execute gdb --args ./XMLTester ....

Hi, changing the configure phase in this mode it seem work.
CFLAGS="-m64" CPPFLAGS="-m64" CXXFLAGS="-m64" LDFLAGS="-m64" FFLAGS="-m64" LDFLAGS="-L/usr/lib64/" ./configure --enable-python
Now the "make check" start and end without any error.
it only report some strange notice like these:

Great to know there's finally no problem building geos. The notices are expected.
Note:
See TracTickets
for help on using tickets.
Can you obtain a backtrace ? If you edit 'testrunner' (it's a shell script) you can add a 'gdb --args' prefix to the ./XMLTester call, the enter 'bt'<enter> when you get the assertion
