tags +upstream thanks Hello Török,
this is clearly an upstream, and not a Debian packaging bug. Adding bug-libtool. * Török Edwin wrote on Sat, Apr 24, 2010 at 09:19:54AM CEST: > ClamAV uses LT_LIB_M to find the math library. > It failed on AIX, see https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1989 > > configure:12861: checking for cos in -lm > configure:12886: gcc -o conftest -DSYSV -D_AIX -D_AIX32 -D_AIX41 -D_AIX43 > -D_AIX51 -D_AIX52 -D_ALL_SOURCE -DFUNCPROTO=15 -O > -I/opt/freeware/include -L/opt/freeware/lib > -Wl,-blibpath:/opt/freeware/lib:/usr/lib:/lib conftest.c -lm >&5 > conftest.c:53: warning: conflicting types for built-in function 'cos' > collect2: library libm not found > configure:12895: result: no > > Looks like the macro looks for cos in -lm, and if it does't find it there, > it assumes that no library is needed for it. > But that is not the case here (the user didn't have libm installed). OK, that's a bug. For the Libtool testsuite (which I have so far thought to be the primary user of LT_LIB_M) the right fix would be to allow another failure action however, so we could skip the test. > I think this macro should fail at configure time, and tell the user to install > libm, if it can't find the cos() function at all. If you need such a macro, then you should write one yourself, and use a math function that you are going to need. It's essentially a one-liner: AC_SEARCH_LIBS([cos], [m], [], [AC_MSG_ERROR([need math library])]) Cheers, Ralf -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
