Hello, The C library function system() seems to always returns -1. But I depend on a working system() function.
I am trying to compile my project ( http://seed7.sourceforge.net/ ) with emcc. The build process uses a C program called chkccomp.c. This program checks the properties of C compiler and run-time library. To do this chkccomp.c uses system() to invoke the C compiler with many small test programs. Depending on this test programs the configuration is written to a configuration header file. In detail a small test program is written to the file ctest.c. After that system("emcc ctest.c"); compiles the program and finally ctest is executed with system("node cctest.js>ctest.out"); . At least this is my plan (and for other compilers this approach works without problems). With emcc this approach does not work. system(NULL) returns -1 and system("DIR") returns also -1 (I do the emcc tests on windows. For other compilers I use also Linux). Maybe I need some option for emcc or node to make system() work. With I have some issues with emcc and chkccomp.c: The program chkccomp.c opens the configuration file in append mode. This does not work. To come around this I decided to write the configuration to stdout instead (and to redirect stdout to my file). Beside this problems a lot of the C source files compile just fine with emcc. Please advice me how system and local files work with emcc.
