$srcdir/configure --enable-languages=ada --disable-libada make [bootstrap] make -C gcc gnatlib-sjlj make install in the $prefix/lib/gcc/$target/$version directory: - create 'sjlj' subdir - move 'adainclude' and 'adalib' subdirs to 'sjlj' subdir rm gcc/stamp-gnatlib* make -C gcc gnatlib-shared gnattools make install You need GCC 3.x or GCC 4.2 for GNAT SJLJ exceptions to work. > From [2] it looks like this is a configure-time option only. [2] describes GCC SJLJ, which is not the same as GNAT SJLJ. -- Eric Botcazou
