**********

The GUI C client builds correctly with same setting.

Environment

Gen COM Proxy

Cause

The BT scripts are located in directory "%Gen86%Gen\bt\scripts".

The COM proxy build script build_proxy_com.scr contains these link settings for the OPT.DEBUG value check:
{[IF]} EQUAL "{$toUpperCase({OPT.DEBUG})}" "YES"
CFLAGS=$(CFLAGS) -Zi -Od -UNDEBUG
DLLLINK=$(DLLLINK) -DEBUG /NODEFAULTLIB MSVCRT.LIB KERNEL32.LIB
EXELINK=$(EXELINK) -DEBUG
{[ENDIF]}

However for the C client build where there is no error the corresponding script build_lm_c.scr section contains these link settings:
{[IF]} EQUAL "{$toUpperCase({OPT.DEBUG})}" "YES"
CFLAGS=$(CFLAGS) -Z7 -Od
DLLLINK=/DEBUG $(DLLLINK)
STUBLINK=/DEBUG $(STUBLINK)
{[ENDIF]}

The build_proxy_com.scr script is out of date and needs to use the same link settings as build_lm_c.scr.

Resolution

The build_proxy_com.scr script will be updated by a future BTN* PTF.

As a workaround, backup the current build_proxy_com.scr and edit it to match the link settings in the build_lm_c.scr for the OPT.DEBUG value check.
