Hello,

I've got a strange problem with building dlls under Win98.
Considering the following example for a batch file:

++++++++++++++++

SET GCC_EXEC_PREFIX=C:\Praktikum_RT2\mingw32\lib\gcc-lib\
SET
LIBRARY_PATH=C:\Praktikum_RT2\mingw32\lib\gcc-lib\i386-mingw32\egcs-2.91.66;
C:\Praktikum_RT2\mingw32\i386-mingw32\lib;C:\Praktikum_RT2\mingw32\lib
SET
C_INCLUDE_PATH=C:\Praktikum_RT2\mingw32\lib\gcc-lib\i386-mingw32\egcs-2.91.6
6\include;C:\Praktikum_RT2\mingw32\i386-mingw32\include;C:\Praktikum_RT2\min
gw32\include
SET CPLUS_INCLUDE_PATH=%C_INCLUDE_PATH%;C:\Praktikum_RT2\mingw32\include\g++
SET OBJC_INCLUDE_PATH=%C_INCLUDE_PATH%

gcc -c -IC:\Praktikum_RT2\CAMeL-VIEW\CSources actuator.c

echo INPUT(C:\Praktikum_RT2\CAMeL-VIEW\CSources\dsc_math.o) > ACTUATOR.lnk
echo INPUT(C:\Praktikum_RT2\CAMeL-VIEW\CSources\s_intpol.o) >> ACTUATOR.lnk
echo INPUT(C:\Praktikum_RT2\CAMeL-VIEW\CSources\dllinit.o) >> ACTUATOR.lnk
echo INPUT(actuator.o) >> ACTUATOR.lnk

echo LIBRARY ACTUATOR > ACTUATOR.def
echo EXPORTS >> ACTUATOR.def
echo model=model AT 0 >> ACTUATOR.def

gcc -mdll -o jnk.dll -Wl,--base-file,ACTUATOR.bas,ACTUATOR.lnk

dlltool --dllname ACTUATOR.dll --base-file ACTUATOR.bas --output-exp
ACTUATOR.exp --def ACTUATOR.def

gcc -mdll -o jnk.dll -Wl,--base-file,ACTUATOR.bas,ACTUATOR.lnk ACTUATOR.exp

+++++++++++++++++

The jnk.dll is loadable when generated under NT in the program running NT.
The jnk.dll is loadable when generated under 98 in the program running NT.
The jnk.dll is loadable when generated under NT in the program running 98.
The jnk.dll is NOT loadable when generated under 98 in the program running
98.
(But we must have this constellation! :( )

We've checked the contents of the object-files - they are identical, but not
the ACTUATOR.exp.

Is it a known problem? Is there a solution?

MfG. Oliver Oberschelp
