GCC contains a standard C++ library file, a header named version [1] which contains macro definitions for information about the C++ standard library. Boost check if this is available [2] and if yes, blindly include that [3] (can it be std/version instead?). This is OK, but libcutl has a version named file [4] as well only containing the project version number. Then in the cutl/ subdirectory re/re.cxx tried to be compiled with the following command line: g++ -DHAVE_CONFIG_H -I.. -I.. -DLIBCUTL_DYNAMIC_LIB -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=[COMPILE_DIRECTORY]/libcutl/libcutl-1.10.0+ds1=. -fstack-protector-strong -Wformat -Werror=format-security -c re/re.cxx -fPIC -DPIC -o re/.libs/re.o Early on it has -I.. to include the libcutl top level source directory to search for headers. This is where its version file found before the standard C++ one. This makes g++ first choke with '../version:1:1: error: too many decimal points in number' then with '../version:1:1: error: expected unqualified-id before numeric constant'. This might be prevented by Boost include std/version (making the path more unique), libcutl to place standard C++ header include paths first or by renaming its version file to version.txt or something like that. I think the Boost solution would be the best, multiple projects might have a 'version' named file. It's not my call, I don't have contact with them. Meanwhile I can remove 'version' from libcutl as it seems it's unused.
