COB_PRE_LOAD and COB_LIBRARY_PATH all the printouts not able to load dll

[J McNamara]

hI i am trying to set the following:

export COB_PRELOAD_PATH-c:/msys64/mingw64/bin/ptr.dll
export COB_PRE_LOAD=c:/msy64/mingw64/bin

cobcrun -r

I am about at wits end on this one.

I set both the system path and the user path to point to c:/msys64/msys64/bin in windows env settings.

I use these to compile ...
g++ -shared -o myptr.dll testabc.c -Wl,--out-implib,myptr.lib
RESET
cd ~/cobjapi-SWING/examples_simple
pwd

Try to remove dialog.o, if it exists

if [ -f "dialog.o" ]; then
rm dialog.o
if [ $? -ne 0 ]; then
echo "Failed to remove dialog.o, but continuing script."
fi
else
echo "dialog.o does not exist, skipping removal."
fi

Try to remove dialog.o, if it exists

if [ -f "dialog.cbsql" ]; then
rm dialog.cbsql
if [ $? -ne 0 ]; then
echo "Failed to remove dialog.o, but continuing script."
fi
else
echo "dialog.o does not exist, skipping removal."
fi
echo 'gixpp'
gixpp -e -S -i dialog.cbl -o dialog.cbsql
echo 'gixsql'
gixsql dialog.cbl dialog.cbsql -S -I.
echo 'cobc'
cobc -x -v -fixed dialog.cbsql cobjapi.o japilib.o imageio.o fileselect.o \
-I. -L"c:\msys64\mingw64\bin" -L"c:\msys64\mingw64\lib" -L"c:\msys64\opt\gixsql\lib" -L. -lws2_32 \
-ljapi \
-lgixsql \
-lstdc++ \
-lcob \
-lmyptr

also i put the dll in c:/msys64/mingw64/bin

any CLUE what is making this go whacko?

A BIG THANKS,
jim

The path goes to COB_LIBRARY_PATH and COB_PRE_LOAD has only the name, here ptr (no path, no file extension).

Okay Simon,

You fixed it again. Hooray!

I am just going to take notes this A.M. and put them in the cherry tree note taking APP.

Thanks for the cool help.

Now, I can read some more Ron Norman docs and play with pointers.

thanks :-)

I do not know if it matters but there is a - (minus sign) instead of = (equal)
export COB_PRELOAD_PATH-c:/msys64/mingw64/bin/ptr.dll

[J McNamara]

sorry Ralph,
I missed the minus when i typed because my vision is not the greatest.

Simon solved it when he told me to use the dll name without the file-path.

It worked immediately after I found that out.

Thank you for pointing that out because that could have been the piece that solved it.
I am going to spend some more time reading Ron Norman's cobol calling C guide etc.
because that is just too cool to pass up.

I'm not very good at it yet but am just starting to try.

Maybe I will screen magnify my email before sending and I have to when putting code down remember text only too.

thanks,
jim
