Hi,

I tried to compile lam-mpi-7.1.1 on the latest Cygwin release and
failed. I know that this isn't a list about LAM MPI but perhaps
somebody was able to compile the package and knows what is wrong
with my approach. I used the following commands:

   configure --prefix=/usr/local/lam-7.1.1 --with-exceptions \
	--with-purify --with-threads=posix --with-trillium \
	--with-rsh="ssh -q" \
	--enable-shared --without-romio --without-cs-fs \
	|& tee log.configure.$SYSTEM_ENV.$MACHINE_ENV
   make |& tee log.make.$SYSTEM_ENV.$MACHINE_ENV

   make install |& tee log.make-install.$SYSTEM_ENV.$MACHINE_ENV

After about an hour I got

...
gcc -O3 -fexceptions -fexceptions -o lamgrow.exe lamgrow.o  
../../share/liblam/.libs/liblam.a ../../share/libltdl/.libs/libltdlc.a
../../share/liblam/.libs/liblam.a(ssi_boot_slurm.o)(.text+0x3c8):ssi_boot_slurm.

Searching in the web showed that other persons had had similar problems.
One suggestion was to have cygipc installed and ipc-daemon2 running.
The Cygwin documentation states that it is deprecated and that I should
use cygserver instead (which I have running as a Windows service).

Has anybody been able to compile lam-mpi? Do I need other options for
"configure"? Thank you very much for any help in advance.

Please let me know if you need more information.

Kind regards

Siegmar
