Bug#992981: autoconf: AC_CHECK_LIB no longer works with g++
Package: autoconf
Version: 2.71-2
Severity: important
When I want to build MPFR with g++, I get:
checking for __gmpz_init in -lgmp... no
configure: error: libgmp not found or uses a different ABI (including static vs shared).
due to
dnl Check if we can link with GMP
AC_CHECK_LIB(gmp, __gmpz_init, [LIBS="-lgmp $LIBS"],
[AC_MSG_ERROR([libgmp not found or uses a different ABI (including static vs shared).
Please read the INSTALL file -- see "In case of problem".])])
in the configure.ac file.
This is a regression: this error disappears if I downgrade to
autoconf 2.69-14.
