The command "set(... PARENT_SCOPE)" should never affect the calling
scope. This improves the Function test to check that such calls in a
subdirectory scope affect the parent but not the child.
Generated makefiles for try-compile projects should never use color
output. On MSYS the color escapes end up in the try-compile output text
because there is no way to identify whether the output is going to a
color-capable terminal. Instead we should just always skip color for
try-compile projects.
When this test was renamed from DumpInformation to SystemInformation the
configured header that points the dump executable to the directory
containing information files was broken. No information has been dumped
by this test for 2 years! This fixes it.
Some SGI compilers define _SGI_COMPILER_VERSION in addition to the old
_COMPILER_VERSION preprocessor symbol. It is more distinctive, so we
should check it in case the old one is ever removed.
The SGI preprocessor /usr/lib/cpp produces bad output on this code:
#if 1
A
#elif 1
B
#else
C
#endif
Both 'A' and 'C' appear in the output! We work around the problem by
using '#elif 1' instead of '#else'.
This fixes detection of the SGI Fortran compiler id in -o32 mode.
This factors code out of cmOrderDirectories::CollectOriginalDirectories
into cmOrderDirectories::AddOriginalDirectories. Later a new call will
be added, and this is more readable anyway.
The ExportImport test drives its Export and Import projects using the
same compiler and flags. This converts the ctest --build-and-test
command lines to use an initial cache file instead of passing all
settings on the command line.
We need a shorter command line to pass through VS 6 on Win98.
This approach reduces duplicate code anyway.
Add System_Parse_CommandForUnix to the KWSys System interface as a
utility to parse a unix-style command line. Move the existing
implementation out of ProcessUNIX. Add a flags argument reserved for
future use in providing additional behavior.
This teaches the ExternalProject module to check the download URL file
name. If it is not a tarball (.tar, .tgz, .tar.gz) it is an error
because UntarFile does not yet understand other archive formats.
When tarball extraction fails we should still cleanup the temporary
extraction directory. Otherwise the next attempt will create a new
directory and the first one will never be removed.
This teaches Modules/Platform/Linux-SunPro-CXX.cmake the -rpath-link flag. The
SunPro C++ compiler does not have a '-Wl,' option, so we just pass the flag
directly.
This problem was exposed by the ExportImport test now that it links an
executable through the C++ compiler with the -rpath-link flag.
