While looking into the native.api sample I also glimpsed at the wpipe1 sample
and found a few things:
* the Linux C sample seems to be based on the Windows sample except for:
o the file is named "rexxaspi1.c" (note the "s") instead of "rexxapi1.c"
for no apparent reason
o renaming "Api" to "Aspi"
o using the "const char *" instead of "PSZ" and the like
o defines INVALID_ROUTINE to be 10 for unknown reasons, as the Windows
version defines it to
be 40 (which matches the Rexx error number "40 Incorrect call to
routine")
* the Linux Rexx sample seems to be based on the Windows sample except for:
o renaming "Api" to "Aspi"
o using a non-exisiting library ("rexxasp1", hence the Linux file named
"librexxasp1.so") in
the code as the CMake generated library is named "libwpipe1.so" such
that "wpipe1" would
have to be used
* the Linux shared library is named "libwpipe1.so" where it should be
probably named "librexxasp1.so"
For this sample there is a CMakeLists.txt file but there are no Windows and
Linux specific Makefiles
as is the case with the native.api sample.
A working Makefile for Linux is:
OOREXX_CFLAGS = -fPIC
DLL_LFLAGS = -shared
# What we want to build.
all: librexxasp1.so
rexxasp1.o: rexxasp1.c
gcc -c rexxasp1.c $(OOREXX_CFLAGS) -o rexxasp1.o
librexxasp1.so: rexxasp1.o
gcc rexxasp1.o ${DLL_LFLAGS} -o librexxasp1.so
clean:
rm -f *.so *.o libwpipe1.so librexxasp1.so
The name of the Linux sample should be probably changed from "rexxasp" to
"rexxapi" which makes more
sense as the sample shows the usage of APIs.
It is a quite confusing situation!

The other api samples on Linux need to be looked over as well.
