Description Keith 2015-08-24 17:16:17 UTC 
Building gdb on Cygwin under Windows 7, the "run" target of sim/ppc/Makefile.in uses "ln psim$(EXEEXT) run$(EXEEXT)" even though configure detects a broken ln. I replaced the ln with cp (like the configure script said it was using) and the build worked. I tried replacing ln with $(LN) but LN wasn't defined in the build's sim/ppc/Makefile.

The relevant bits from running configure:
checking whether ln works... no, using cp
checking whether ln -s works... no, using cp -p

The relevant bit from the build:
gcc/4.9.2/gdb-7.8.1/sim/ppc/main.c
i686-pc-mingw32-gcc -O2 -pipe -D__USE_MINGW_ACCESS  -static-libstdc++ -static-libgcc -s -Wl,--stack,12582912 -o psim.exe main.o libsim.a ../../bfd/libbfd.a ../../intl/libintl.a ../../libiberty/libiberty.a 
rm -f run.exe
ln psim.exe run.exe

Comment 1 Mike Frysinger 2021-10-03 15:38:07 UTC 
should be fixed now by falling back to symlinks and then copy
