on CYGWIN, Singular LIB files get copied to SAGELOCAL/lib

[dimpase]

On CYGWIN, the Singular LIB files, i.e. files with code in Singular language, normally installed to SAGELOCAL/share/singular/, also get copied to SAGELOCAL/lib/. This, apart from being plainly wrong, is breaking the installation of pyOpenSSL, as mentioned in comments on #13339.

Depends on #13237

I agree that's wrong.
did you check that everything was ok on a Linux install?
I won't have any at hand before tomorrow.

Quite strangely my install log says:

./mkinstalldirs /home/jp/sage-5.2/local/share/singular
mkdir /home/jp/sage-5.2/local/share/singular
for file in `pwd`/LIB/*.lib; do \
  /usr/bin/install -c -m 644  $file /home/jp/sage-5.2/local/share/singular; \
done

while make install-nolns in Singular
And then

./mkinstalldirs /home/jp/sage-5.2/local/LIB
for file in `pwd`/LIB/*.lib; do \
  /usr/bin/install -c -m 644  $file /home/jp/sage-5.2/local/LIB; \
done

while make install-libsingular in Singular.

I guess some Makefile is broken for Cygwin as in #12089.

It's OK on MacOSX and on Linux.

Could you post the install logs here please?
I should have a Linux install in a few minutes, but that could be useful.

The problem should be that we call

$MAKE slibdir="$SAGE_LOCAL/share/singular" install-nolns

but

$MAKE install-libsingular

although that does not explain the discrepancy between Cygwin and other systems.

here is a log of Linux install:

And maybe make install-nolns is rerun as a dependency of make install-libsingular on Cygwin, but not on the other systems where it may be considered uptodate?

Indeed, you only have:

g++ -shared -shared -o libsingular.so \
	iparith.o mpsr_Tok.o claptmpl.o \
	grammar.o scanner.o attrib.o blackbox.o eigenval_ip.o extra.o fehelp.o feOpt.o ipassign.o ipconv.o ipid.o iplib.o ipprint.o ipshell.o newstruct.o lists.o sdb.o fglm.o interpolation.o silink.o ssiLink.o subexpr.o janet.o wrapper.o libparse.o sing_win.o gms.o pcv.o maps_ip.o walk.o walk_ip.o cntrlc.o misc_ip.o calcSVD.o pipeLink.o Minor.o MinorProcessor.o MinorInterface.o bigintm.o pyobject_setup.o bbcone.o bbfan.o denom_list.o minpoly.o  slInit_Dynamic.o -lkernel -L../kernel -L../factory -L../libfac -L/usr/local/src/sage/sage-5.2/local/lib -lsingfac -lsingcf -lntl -lreadline -lgmp -lomalloc
./mkinstalldirs /usr/local/src/sage/sage-5.2/local/include/singular
for file in *.so; do \
	  /usr/bin/install -c  $file /usr/local/src/sage/sage-5.2/local/lib; \
	done

but that's an old spkg, I'd like to also check the later ones (I could also look into the old spkg sources but i'm lazy).

Your Cygwin log is similar to mine.

I'm currently building your 3-1-5.p1 on MacOSX. I'll see what I get soon, and post the log, too.

the problem is reproducible on MacOSX, too. I got all these singular's lib-files in SAGELOCAL/lib, too

I checked the Makefile sources. Indeed, $MAKE install-libsingular shares a dependency of $MAKE install-nolns. Whether it will be rebuilt or not might depend on the actual make implementation, so I'll recommend to add slibdir="$SAGE_LOCAL/share/singular" to all calls of make. (Unfortunately slibdir is not a configurable variable.) Perhaps we should add it to $MAKE?
