Summary0014917: CMake does nor create response file for Ninja
DescriptionOn a larger project, (cmake -G Ninja) the arguments get too long for Ninja or Linux to handle.
(That's usually the link command).
Linking aborts because of error command line too long
Steps To Reproducehappens always if link command is long enough
Additional InformationI have a work-around for this:

ninjaFix.lex:

%%
CXX_EXECUTABLE_LINKER printf("%s_RSP_FILE", yytext);
TARGET_PDB.+ printf("%s/n RSP_FILE = rsp.txt\n", yytext);
 

flex ninjaFix.lex
gcc -o fix lex.yy.c -lfl

and then I do after cmake -G Ninja:

mv build.ninja build.ninja.in
fix < build.ninja.in > build.ninja

and then I can call ninja -j 20 without an error.


Would be great if this fix could be integrated into the Ninja generator of cmake !

There was a recent patch which fixed some command line length limits. As a workaround, there is the CMAKE_NINJA_FORCE_RESPONSE_FILE which will force response files for all targets.

Ok, great! What version of cmake do I need to require for that option to work?
