Bug ID: 18864
Summary: Power PC build fails on Cygwin due to use of ln.
Product: gdb
Version: 7.9
Status: NEW
Severity: critical
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: kpublic at tranaptic dot ca
Target Milestone: ---

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
