Hi,

I'm using svn release 4417 for now. Anyway, it builds the object files inside the source directory!


--- Code: ---tricore-gcc.exe -mcpu=tc1775 -O2 -fno-short-enums -fno-common -W -Wall -g -DERT=1 -DMODEL=phycore1775_led -DNUMST=1 -DNCSTATES=0 -DHAVESTDIO -DADD_MDL_NAME_TO_GLOBALS=1 -DONESTEPFCN=1 -DTERMFCN=1 -DMAT_FILE=0 -DMULTI_INSTANCE_CODE=0 -DINTEGER_CODE=0 -DMT=0 -DMULTITASKING=0 -DTID01EQ=0 -g  -IC:\Programme\MATLAB\R2007a\rtw\c\libsrc -I"D:\Dokumente und Einstellungen\olpetzol\Eigene Dateien\MATLAB\phycore1775_led_tricore_ert"  -c C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubcc_sgl.c -o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubcc_sgl.o
...

--- End code ---

I would expect the object files located relative to the project directory as the project settings  suggest:


And now: the real confusing:


--- Code: ---...
tricore-ar.exe -rs build\debug\librtw.a C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubcc_sgl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrc_dbl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrc_sgl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrr_dbl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrr_sgl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubcc_dbl.o

-------------- Build: Release in rtwlib ---------------
tricore-ar.exe -rs librtw.a C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubcc_sgl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrc_dbl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrc_sgl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrr_dbl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubrr_sgl.o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubcc_dbl.o

--- End code ---

The lib builds/created twice, in the project's defined directory and the current (c::b project's) directory!

Did I missunderstand something or is the bug not fixed correctly (maybe another one)?

Thanks
Olaf

I wrote it earlier that in case the source file is in different drive, the object file would be build at the source location.

If the source directory is in different drive, the relative path creation fails and it uses the full path instead. This is currently hard-coded. But this can be changed.

It's not created twice. Rather both of your targets are being built at the same time.

The effect is, that two libs are created! One in build\debug\librtw.a and one inside the work directory; since the depency is related to librtw.a in the work/project directory, the release target (from virtual "all") will not be created!

Please post one such working example.

a) The objects of the library are not inside the given object_output object dir (target depend)
b) Therefore the release target lib is build on debug build objects

The Problem is related to gcc's outfile option -o C:\Programme\MATLAB\R2007a\rtw\c\libsrc\rt_backsubcc_sgl.o which should be
-o build\debug\rt_backsubcc_sgl.o as the binary output object directory tag promised - regardless if the source point to windows drive c:\ and/or the build is on drive d:\

The same with the ar command line.

It seems the path from source files are not stripped correctly for object files.

Olaf
