Good catch. I've commented code and found the error is in the function
rule check-message-compiler ( properties * )
I've changed the line 117:
if <target-os>windows in $(properties)
to
if <target-os>windows in $(properties) && !<toolset>gcc in $(properties)
and the error goes away. It seems that the line 121:
local has_mc = \
[ configure.builds (...) : $(properties) : message-compiler ] ;
is where the problem lies.
The Boost.log documentation states that "at some point the library will
require a Message Compiler tool (mc.exe), which is not available in
MinGW, Cygwin and some versions of MSVC Express Edition". The check
seems to hurt Boost.Build when using a MINGW environment.
I don't know if my change makes any sense as windows supports many
compilers (clang, intel, borland, ) so maybe the "if" condition should
be more complex. I've applied the change locally and regression tests
are up again.
Best,
Ion
