Wildcards no longer supported?

[Leo Havmøller]

It seems *.o wildcard for linking is no longer supported in 2014q1:
<pre>
Linking CoreTest.hex
"""C:\Program Files (x86)\GNU Tools ARM Embedded\4.8 2014q1\bin\arm-none-eabi-gc
c.exe" -specs=nano.specs -LD:\Work_OS5x\Include -mcpu=cortex-m0 -mthumb -Wl,-sta
tic -Wl,-nostdlib -Wl,--cref -Wl,--gc-sections -Wl,-Map=CoreTest.map Obj\\*.o
-T CoreTest.def -L"C:\Program Files (x86)\GNU Tools ARM Embedded\4.8 2014q1\lib"
  -o CoreTest.elf""
arm-none-eabi-gcc.exe: error: Obj\\*.o: Invalid argument
</pre>

Was OK in 2013q4 and earlier:
<pre>
Linking CoreTest.hex
"""C:\Program Files (x86)\GNU Tools ARM Embedded\4.8 2013q4\bin\arm-none-eabi-gc
c.exe" -specs=nano.specs -LD:\Work_OS5x\Include -mcpu=cortex-m0 -mthumb -Wl,-sta
tic -Wl,-nostdlib -Wl,--cref -Wl,--gc-sections -Wl,-Map=CoreTest.map Obj\\*.o
-T CoreTest.def -L"C:\Program Files (x86)\GNU Tools ARM Embedded\4.8 2013q4\lib"
  -o CoreTest.elf""

Issue is confirmed. Probably because we use new mingw build environment to produce windows tool chain. I am looking into it. Thanks for reporting.

[Terry Guo (terry.guo)]

To support wildcard, we need to configure mingw runtime library with option --enable-wildcard during the setup of mingw build environment. By default it is disabled. The 4.8 Q2 update release should fix this issue.

For the time being, this issue can be workaround by following steps:

1) add below line right before the gcc link command to save all object file names into a file.
for %i in (Obj\*.o) do @echo Obj\\%~nxi >> f.list

2) now execute normal gcc link command like below:
arm-none-eabi-gcc YOUR-OPTIONS @f.list

3) remove the a.list file.

Another simple way is to replace Obj\*.o with actual file names. Those are all that I can conceive. Sorry for the inconveniences caused by this bug.

tested with gcc-arm-none-eabi-5_4-2016q3-20160926-win32

It seems *.o wildcard for linking is no longer supported in 2016q3:

I'm sorry but we can't reproduce this bug. Can you double check the version you are using?
