Hi,
I've just installed ghdl with llvm-backend under Ubuntu 16.04 LTS
and ran into a strange issue.
All builds apparently fine, but when I use ghdl to compile a model I got
gcc: error: .../usr_local/lib/ghdl/v93/std/std_standard.o:
No such file or directory
ghdl: compilation error
Indeed lib/ghdl/v93/std/std_standard.o is missing. Turns out that
in the ghdl compile directory is a std_standard.o, and just moving
it to the lib/ghdl/v93/std fixes it.
Looking into the compile log file I see
mkdir -p lib/ghdl/v08
...
cd lib/ghdl/v93/std; \
.../ghdl/ghdl_llvm --bootstrap- standard \
--GHDL1=.../ghdl/ghdl1-llvm --std=93
cd lib/ghdl/v87/std; \
.../ghdl/ghdl_llvm --bootstrap-standard \
--GHDL1=.../ghdl/ghdl1-llvm --std=87
/bin/sh: 1: cd: can't cd to lib/ghdl/v87/std
/bin/sh: 1: cd: can't cd to lib/ghdl/v93/std
apparently lib/ghdl/v08 is created in time, but lib/ghdl/v93/std
and lib/ghdl/v87/std aren't at the time they are needed.
Seems to be an issue with the make file. I use
time git clone https://github.com/tgingold/ghdl
cd ghdl
mkdir usr_local
./configure --with-llvm-config=/usr/lib/llvm-3.5/bin/llvm-config \
--prefix=`pwd`/usr_local
time make -j 2 2>&1 | tee compile.log
make install 2>&1 | tee install.log
and wonder why that leads to such strange results.
Any hint/help very welcome.
With best regards, Walter
