COBOL

Please paste a snippet of your makefile where these export commands are so I can see them in context. Also, what happens if you remove the colon ':' from the assignments?

Makefile Code

# ********************
# *** Set Commands ***
# ********************

RM      := rm
RMFLAGS := -rf

# *******************************
# *** Environment C Variables ***
# *******************************

export C_INCLUDE_PATH := include

# ***********************************

export SYSLIB    := include:include/reymon
export COBOPT    := 
export COBCPYEXT := .cpy
export COBLSTDIR := build/list

# ************************************
# *** Environment Linker Variables ***
# ************************************

export LIBRARY_PATH := lib

Instead of "-q64", specify "addr(64)" (including the quotes). However, note that this option is not necessary since the default compilation mode for the V1.2 compiler is 64 bit.

Regarding COBCPYEXT, please paste the exact line from your source that contains the COPY statement, and also do an "ls" to show the .cpy file in the filesystem and paste that output. 

The exact code for the copy command is COPY "file/control/reydb.cpy". This is because I was unable to use COBCPYEXT and the ls is in include/file/control

I can try to determine why COBCPYEXT isn't working for you, but I'll need to see the original COPY statement before you changed it to work around the problem. Thanks
