Cannot compile v1.9 under cygwin

[gradoj]

I'm having trouble compiling v1.9 using cygwin. I don't have any trouble with 1.8.7. Any help appreciated:

mkdir -p build-PYBV11/usbdev/core/src/ MPY modules/lcd160cr.py MPY modules/lcd160cr_test.py Create stmconst build-PYBV11/genhdr/modstm_const.h Traceback (most recent call last): File "modules/lcd160cr.py", line 1 SyntaxError: invalid syntax Traceback (most recent call last): File "modules/lcd160cr_test.py", line 1 SyntaxError: invalid syntax make: *** [../py/mkrules.mk:117: build-PYBV11/frozen_mpy/lcd160cr.mpy] Error 1 make: *** Waiting for unfinished jobs.... make: *** [../py/mkrules.mk:117: build-PYBV11/frozen_mpy/lcd160cr_test.mpy] Error 1 Create build-PYBV11/pins_PYBV11.c
I deleted LCD160cr.py cause I do not need it but I then get:

This is a duplicate of #2961: symlinks don't work on cygwin so you either need to copy the files (in this case lcd160cr.py) or delete them. After deleting them (everything in stmhal/modules/) try doing "make clean", then it should work.

I will have to compile on a linux machine. I get the errors above if I leave or delete the py sym link file and I get this linking problem if I copy the files from drivers into the module directory:

CC build-PYBV11/frozen_mpy.c
LINK build-PYBV11/firmware.elf
/bin/sh: -c: line 0: syntax error near unexpected token `('
/bin/sh: -c: line 0: `arm-none-eabi-ld -nostdlib -L boards -T boards/stm32f405.ld -Map=build-PYBV11/firmware.map --cref --gc-sections -o build-PYBV11/firmware.elf build-PYBV11/py/mpstate.o build-PYBV11/py/nlrx86.o build-PYBV11/py/nlrx64.o build-PYBV11/py/nlrthumb.o....

To completely disable the frozen bytecode, try running the following (in stmhal/ dir):

$ make FROZEN_MPY_DIR=

If it still fails, please run make V=1 FROZEN_MPY_DIR= and report the results.

Looks like i'm getting the same linker error as above. I also upgraded the compiler to the latest 6.3.1 feb 2017 with no change. Attached verbose output.

The issue is that your libgcc.a exists in directory with "(" and ")" in it, namely c:/program files (x86)/gnu tools arm embedded/6 2017-q1-update/bin/../lib/gcc/arm-none-eabi/6.3.1/thumb/v7e-m/fpv4-sp/hard/libgcc.a. This filename needs to be correctly quoted and/or escaped for it to work. (This wasn't an issue in v1.8.7 because libgcc.a was not used in that version.)

You can try changing line 64 of stmhal/Makefile to have quotes like this:

LIBS = "$(shell $(CC) $(CFLAGS) -print-libgcc-file-name)"

Otherwise, if this doesn't work, try changing this line to simply LIBS = . You don't really need the library.

[gradoj]

The quotes worked for me. Thanks.

LIBS = "$(shell $(CC) $(CFLAGS) -print-libgcc-file-name)"

Just want to add, if you enable symlinks -c core.symlinks=true while cloning the repo I'm able to successfully compile.
