One of the PLplot developers has been using the macada version of the gcc

but he has recently run into build problems for cmake-2.6.
The issue can be illustrated by a simple "hello-world" shared library
build test project with SOVERSION and VERSION specified for the library.
You can svn checkout that simple test from
https://plplot.svn.sourceforge.net/svnroot/plplot/branches/test_cmake/test_
c_library_build
His platform is OS X version 10.4.11 on a ppc processor.
I present three different VERBOSE=1 "make" output results that he obtained
with the above simple test project.
I) CMake-2.6.2 using the standard Apple compiler with the following gcc -v
results:
Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /private/var/tmp/gcc/gcc-5363.obj~28/src/configure --
disable-checking -enable-werror --prefix=/usr --mandir=/share/man --
enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg]
[^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --with-
slibdir=/usr/lib --build=powerpc-apple-darwin8 --host=powerpc-apple-
darwin8 --target=powerpc-apple-darwin8
Thread model: posix
gcc version 4.0.1 (Apple Computer, Inc. build 5363)
For this compiler all is well for CMake-2.6.2 (see the attached
make.out_gcc_std_2.6.2). However, note he cannot use that standard compiler
for his ordinary PLplot development that strongly focusses on Ada.
II) CMake-2.4.8 using the macada gcc compiler with the following gcc -v
results:
Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /Users/drew/Developer/Compiler/gcc-head/configure
--disable-checking --disable-nls --enable-static
--prefix=/usr/local/ada-4.3 --host=powerpc-apple-darwin8
--target=powerpc-apple-darwin8
--build=powerpc-apple-darwin8
--enable-languages=c,ada,c++,fortran,objc,obj-c++
Thread model: posix
gcc version 4.3.0 20070904 (experimental) [trunk revision 128067] (GCC)
For this compiler all is well for CMake-2.4.8 (see the attached
make.out_gcc_macada_2.4.8). The macada compiler package also provides an
integrated Ada compiler so this is the one he has been using for his PLplot
development. Note, the linking for 2.4.8 is done without use of the
-current_version flag.
III) CMake-2.6.2 using the macada gcc compiler with the above
gcc -v results. For this compiler all is not well for CMake-2.6.2 (see the
attached make.out_gcc_macada_2.6.2). The -current_version
flag used by CMake-2.6.2 is not recognized by this compiler (or probably
more likely the linker associated with this compiler).
Is there some symbol defined which could be tested e.g. in
Modules/CMakeCCompilerId.c.in ?
What is the output of macada gcc with this command line:
gcc -E -dM -x c /dev/null
?
