Gute nacht Rony
I have an atypical configuration where I use DYLD_LIBRARY_PATH to locate the
BSF4OORexx library.
This is because I don’t “install” BSF4OORexx, I just unzip the delivery, copy
and rename the libraries to bsf4oorex/install/64
With this configuration, your test cases are working (not saying this is the
solution).
If I don’t set DYLD_LIBRARY_PATH, I get the same error than yours.
I compared the output of the next command in both cases
DYLD_PRINT_LIBRARIES="1" DYLD_PRINT_APIS="1" rexx -e "call bsf.cls”
In the working session:
dlopen(librexxapi.dylib, 0x00000001)
dlopen(librexxapi.dylib) ==> 0x10936da50
dlopen(libBSF4ooRexx.dylib, 0x00000001)
dyld: loaded:

Error 98.903: Unable to load library "BSF4ooRexx".
I find "/usr/lib” in one file:
SysLibrary.cpp
// try loading directly
libraryHandle = dlopen(nameBuffer, RTLD_LAZY);
// if not found, then try from /usr/lib
if (libraryHandle == NULL)
{
sprintf(nameBuffer, "/usr/lib/lib%s%s", name, ORX_SHARED_LIBRARY_EXT);
libraryHandle = dlopen(nameBuffer, RTLD_LAZY);
The part to investigate is how to make the first dlopen work without using
DYLD_LIBRARY_PATH:
If I put libBSF4ooRexx.dylib in the lib folder of oorexx then it works (RPATH).
If I put libBSF4ooRexx.dylib in the current directory then it works (see man
dlopen).
I don’t know if other solutions are possible for the first dlopen
The other solution could to add “/usr/local/lib” as 2nd fallback.
But that brings the question of order.
Maybe a more general solution would be to use an environment variable like
REXX_LIBRARY_PATH.
We have already REXX_PATH for locating the rexx files.
