The newline parameter isn't hard to reproduce (just use istr.eof() right after the getline() succeeds), but the sizeLimit parameter is harder :( . We could hack it up with a custom max_size() method on a custom std::basic_string subclass, but that sounds awful. > Yes, please try this. Mojca, how did you bootstrap cmake to use libc++ and clang?

If that actually worked on all old stream libraries then we would
not need GetLineFromStream. Also GetLineFromStream has a separate
output argument for indicating whether the line ended in a newline.

Yes, please try this.

The proper way to read lines from a file using iostream is:
std::string line;
while (std::getline(istr, line)) {
// use line
}
Unfortunately, it looks like there's unavoidable extra logic in there.
Maybe we could do:
#ifdef BROKEN_STREAMS
// crutch code
#else
// sanity
#endif

[cmake-developers] Weird build error against libc++ on OS X 10.7 (cutting at 1024 characters)
Dear CMake developers, I tried to compile CMake against libc++ on OS X 10.7. For a weird reason it fails: Built target cmsysTestsC [ 25%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/frm_scale.c.o [ 25%] Building CXX object Source/kwsys/CMakeFiles/cmsys.dir/IOStream.cxx.o [ 25%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/frm_sub.c.o [ 25%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/frm_user.c.o [ 26%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/frm_win.c.o [ 26%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_alnum.c.o [ 26%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_alpha.c.o [ 27%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_enum.c.o [ 27%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_int.c.o [ 27%] [ 27%] Building CXX object Source/kwsys/CMakeFiles/cmsys.dir/SystemInformation.cxx.o Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_ipv4.c.o [ 28%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_num.c.o [ 28%] Building C object Source/CursesDialog/form/CMakeFiles/cmForm.dir/fty_regex.c.o Linking C static library libcmForm.a ar: C: No such file or directory make[2]: *** [Source/CursesDialog/form/libcmForm.a] Error 1 make[2]: Leaving directory `/path/to/cmake-3.0.0' make[1]: *** [Source/CursesDialog/form/CMakeFiles/cmForm.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs Linking CXX static library libcmsys.a make[2]: Leaving directory `/path/to/cmake-3.0.0' [ 28%] Built target cmsys make[1]: Leaving directory `/path/to/cmake-3.0.0' make: *** [all] Error 2 When I use "make" again and a single core, it fails with [ 66%] Building CXX object Source/CMakeFiles/CMakeLib.dir/cmNinjaUtilityTargetGenerator.cxx.o cd /path/to/cmake-3.0.0/Source && /usr/bin/clang++ -DCMAKE_BUILD_WITH_CMAKE -pipe -Os -arch x86_64 -stdlib=libc++ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk -mmacosx-version-min=10.7 -I/path/to/cmake-3.0.0/Utilities -I/path/to/cmake-3.0.0/Source -I/opt/libcxxlocal/include -I/path/to/cmake-3.0.0/Utilities/cmcompress -I/path/to/cmake-3.0.0/Source/CTest -I/path/to/cmake-3.0.0/Source/CursesDialog/form-o CMakeFiles/CMakeLib.dir/cmNinjaUtilityTargetGenerator.cxx.o -c /path/to/cmake-3.0.0/Source/cmNinjaUtilityTargetGenerator.cxx Linking CXX static library libCMakeLib.a cd /path/to/cmake-3.0.0/Source && /path/to/cmake-3.0.0/Bootstrap.cmk/cmake -P CMakeFiles/CMakeLib.dir/cmake_clean_target.cmake cd /path/to/cmake-3.0.0/Source && /path/to/cmake-3.0.0/Bootstrap.cmk/cmake -E cmake_link_script CMakeFiles/CMakeLib.dir/link.txt --verbose=1 /usr/bin/ar cr libCMakeLib.a CMakeFiles/CMakeLib.dir/cmStandardIncludes.cxx.o CMakeFiles/CMakeLib.dir/cmArchiveWrite.cxx.o CMakeFiles/CMakeLib.dir/cmBootstrapCommands1.cxx.o CMakeFiles/CMakeLib.dir/cmBootstrapCommands2.cxx.o CMakeFiles/CMakeLib.dir/cmCacheManager.cxx.o CMakeFiles/CMakeLib.dir/cmCommands.cxx.o CMakeFiles/CMakeLib.dir/cmCommandArgumentLexer.cxx.o CMakeFiles/CMakeLib.dir/cmCommandArgumentParser.cxx.o CMakeFiles/CMakeLib.dir/cmCommandArgumentParserHelper.cxx.o CMakeFiles/CMakeLib.dir/cmComputeComponentGraph.cxx.o CMakeFiles/CMakeLib.dir/cmComputeLinkDepends.cxx.o CMakeFiles/CMakeLib.dir/cmComputeLinkInformation.cxx.o CMakeFiles/CMakeLib.dir/cmComputeTargetDepends.cxx.o CMakeFiles/CMakeLib.dir/cmCryptoHash.cxx.o CMakeFiles/CMakeLib.dir/cmCustomCommand.cxx.o CMakeFiles/CMakeLib.dir/cmCustomCommandGenerator.cxx.o CMakeFiles/CMakeLib.dir/cmDefinitions.cxx.o CMakeFiles/CMakeLib.dir/cmDepends.cxx.o CMakeFiles/CMakeLib.dir/cmDependsC.cxx.o CMakeFiles/CMakeLib.dir/cmDependsFortran.cxx.o CMakeFiles/CMak ar: CMakeFiles/CMak: No such file or directory make[2]: *** [Source/libCMakeLib.a] Error 1 make[1]: *** [Source/CMakeFiles/CMakeLib.dir/all] Error 2 make: *** [all] Error 2 The weird part is that part of the command is simply "cut off": CMakeFiles/CMakeLib.dir/cmDependsFortran.cxx.o CMakeFiles/CMak I looked into Source/CMakeFiles/CMakeLib.dir/link.txt.
