Keywords: "make check" cygchicken-0.dll

Description

It seems that cygchicken-0.dll is expected to be found in the tests directory:

 $ make PLATFORM=cygwin PREFIX=/home/mario/local/chicken-core DEBUGBUILD=1 CHICKEN=./chicken-boot check
 make -f ./Makefile.cygwin CONFIG= check
 make[1]: Entering directory `/home/mario/src/chicken-core'
 cd tests; sh runtests.sh
 ======================================== compiler tests ...

 hicken"
 rm a.c
 gcc a.o -o a.out -L.. -L"/home/mario/local/chicken-core/lib" -lchicken -lm
 rm a.o
 /home/mario/src/chicken-core/tests/a.out: error while loading shared libraries:

 make[1]: *** [check] Error 127
 make[1]: Leaving directory `/home/mario/src/chicken-core'
 make: *** [check] Error 2

If I

 cp cygchicken-0.dll tests

some tests can be run, but then:

 $ make PLATFORM=cygwin PREFIX=/home/mario/local/chicken-core DEBUGBUILD=1 CHICKEN=./chicken-boot check
 
 ...

 rm a.c
 gcc a.o -o a.out -L.. -L"/home/mario/local/chicken-core/lib" -lchicken -lm
 rm a.o

Happens to both 4.7.0 and git HEAD.

I cannot reproduce this error on Linux systems.

The first problem is almost certainly because DLL files have to be either in the current directory or on the $PATH. This is a Windows misfeature that Cygwin cannot hide, because DLLs are loaded by the Windows dynamic loader before Cygwin gets control. (It doesn't apply to DLLs explicitly opened with dlopen().)

Indeed, John. Thanks for reminding me about that. I had a patch to fix that issue, but it breaks tests on other platforms (http://lists.gnu.org/archive/html/chicken-hackers/2011-09/msg00051.html).

I've moved the callback part to #738.
