Hi. I'm the maintainer of the Debian package for Autoconf. I received the following bug report against Autoconf 2.52. It looks like it still applies to Autoconf 2.53, so I'm passing it along upstream with this message.
Thanks, Ben. -------------------- Start of forwarded message -------------------- Subject: Bug#138666: autoconf: AC_EXEEXT fails when CFLAGS="-fprofile-arcs -ftest-coverage" Reply-To: & Youngman <[EMAIL PROTECTED]>, [EMAIL PROTECTED] From: & Youngman <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Message-Id: <[EMAIL PROTECTED]> Date: Sat, 16 Mar 2002 23:39:39 +0000 (GMT) Package: autoconf Version: 2.52-6 Severity: normal If you have a configure script which uses AC_EXEEXT, and the environment variable CFLAGS has been set to "-fprofile-arcs -ftest-coverage" in order to set up for measuring the test suite coverage of a GNUish program with a test suite, then AC_EXEEXT guesses wrongly about the executable suffix. AC_EXEEXT guesses on Unix that the executable suffic is ".bbg". The reason for this is that the GCC compiler will have produced a conftest.bbg file in the current directory, and this file will be picked up in the loop over conftest.* files that AC_EXEEXT performs. This means simply that *.bbg and *.bb should be added to the list of files to ignore in aclang.m4, along with the existing list which includes *.o | *.obj | *.xcoff | *.tds | *.d | *.pdb. This list is near line 670 of aclang.m4 in version 2.52 of autoconf. -------------------- End of forwarded message -------------------- -- "I knew it was a bad sign when I drove through Hell (MI) on Wednesday and there was snow on the ground and all the standing water had a layer of ice on the surface...
