libtool fails without a CXX compiler installed
(Example is from compiling pkgconfig): Without g++ installed: checking whether we are using the GNU C++ compiler... no checking whether g++ accepts -g... no checking dependency style of g++... none checking how to run the C++ preprocessor... /lib/cpp configure: error: C++ preprocessor /lib/cpp fails sanity check See `config.log' for more details config.log: ... configure:4894: /lib/cpp conftest.cc cpp: conftest.cc: C++ compiler not installed on this system configure:4900: $? = 1 ... Compiles fine with g++ installed. However, when I check the compile log it never calls g++, just checks for its existence and fails out.

Re: libtool fails without a CXX compiler installed
Quoting Bob Friesenhahn [EMAIL PROTECTED]: snip The problems I have heard about up until now have been that autoconf found a C++ compiler, but it was discovered not to work. In this case, autoconf's macro throws up its hands and spontaneously quits. So libtool is not working if there is no C++ at all? Correct. I built my system without g++ installed. Then added xorg, which needs pkgconfig down the dependency line, but that failed. I installed g++ and then pkgconfig would compile fine. After some tests of pkgconfig 0.17.2, 0.16.0, and 0.15.0 I found that the first two fail without g++ installed, but the last, 0.15.0, works fine without g++ installed. I filed a bug[0] with pkgconfig and they told me that libtool is where the failure is occurring even though an older version of pkgconfig worked fine. -sandalle [0] https://bugs.freedesktop.org/show_bug.cgi?id=3376 -- Eric Sandall| Source Mage GNU/Linux Developer eric at sandall.us PGP: 0xA8EFDD61 | http://www.sourcemage.org/ http://eric.sandall.us/ | SysAdmin @ Inst.

Sorry. Before libtool 2.0 is released, someone needs to make sure that the libtool/libltdl configuration macros documented in the documentation actually work. One way to know for sure is to incorporate them in the libtool test suite.

There are some changes to the behavior of libtoolize and where the libtool m4 files are stored for the project so some small effort will be required to update to 2.0. The scheme for configuring libltdl has been completely re-vamped in that now the same configure script which configures the package can also configure libltdl without using a subordinate configure script. At least that is the plan.

If your configure script is calling AC_PROG_CXX then you will have to use a similar workaround to libtool: pushdef([AC_MSG_ERROR], [CXX=no]) AC_PROG_CXX popdef([AC_MSG_ERROR]) AM_CONDITIONAL(HAVE_CXX, [test -n $CXX ( test X$CXX != Xno ( (test X$CXX = Xg++ `g++ -v /dev/null 21` ) || (test X$CXX != Xg++)))]) Note that all the tests are not really necessary, but...
