configure.ac needs updating for autoconf 2.69 #16

Closed JohnCremona closed 5 years ago

JohnCremona commented 8 years ago

When run with a current autoconf (2.69), autoconf gives several errors all similar to:

configure.ac:15: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body ../../lib/autoconf/lang.m4:193: AC_LANG_CONFTEST is expanded from... ../../lib/autoconf/general.m4:2661: _AC_LINK_IFELSE is expanded from... ../../lib/autoconf/general.m4:2678: AC_LINK_IFELSE is expanded from... m4/libtool.m4:1022: _LT_SYS_MODULE_PATH_AIX is expanded from... m4/libtool.m4:4161: _LT_LINKER_SHLIBS is expanded from... m4/libtool.m4:5236: _LT_LANG_C_CONFIG is expanded from... m4/libtool.m4:138: _LT_SETUP is expanded from... m4/libtool.m4:67: LT_INIT is expanded from... configure.ac:15: the top level

Solutions welcome since as usual the autotools documentation is extremely opaque.

Closing since there are now no problems using autoconf 2.69. The AC_PREREQ still requires only 2.65, no change.
