GIMP fails to compile without C++ compiler?

Hija,

just curious, is it expected that configuration of a GIMP build will fail if configure cannot find a C++ compiler?

... checking for dlfcn.h... yes
checking for g++... no
checking for c++... no
checking for gpp... no
checking for aCC... no
checking for CC... no
checking for cxx... no
checking for cc++... no
checking for cl... no
checking for FCC... no
checking for KCC... no
checking for RCC... no
checking for xlC_r... no
checking for xlC... no
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.

By supplying a C++ compiler via CXX env variable it happily passes that point:
...
checking for dlfcn.h... yes
checking whether we are using the GNU C++ compiler... yes checking whether g++-3.4 accepts -g... yes checking dependency style of g++-3.4... gcc3 checking how to run the C++ preprocessor... g++-3.4 -E checking for g77... no
...

config.log unfortunately doesn't tell anything sensible...

Servus, Daniel

Hi,

That question would better be asked on the autoconf list. While you are on it, ask them why there are checks for a fortran compiler. I don't think we ask for any of those.

It's a difference whether useless checks take place and are ignored or the compiler bails out on something that isn't needed at all. FWIW I haven't seen any other project using autoconf as well fail on this machine because there wasn't a C++ compiler installed so I assume that the GIMP (or maybe the GNOME stuff?) is doing something different or even wrong.

Servus, Daniel

You're making a bad assumption then. Any app which uses libtool 1.5 has this issue, as a trivial web search will reveal.

There's really nothing we can do, short of updating to a post 1.5 libtool when the libtool maintainers actually release one.

As Yosh has already replied, this is a problem in libtool. I thought a fix had been applied to the 1.5 branch, but I can't seem to find it so it must be in the 2.0 branch only.
