I'm having a problem with the linker not finding a library.
The error message is:
c:/nxp/lpcxpresso_4.3.0_1023/lpcxpresso/tools/bin/../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -lCMSISv2_LPC17xx
I have seen the messages here about not using the correct CMSIS version and I don't think that is the problem in my case.
If I go to Properties/Linker/Libraies, I have this under Search Paths:
"${workspace_loc:/CMSISv2_LPC17xx/Release}"
However, this is the generated linker command line:
arm-none-eabi-gcc -nostdlib -Xlinker -Map=GPIO.map -Xlinker --gc-sections -mcpu=cortex-m3 -mthumb -T "GPIO_Release.ld" -o"GPIO.axf" ./src/IOtest.o ./src/cr_startup_lpc176x.o -lCMSISv2_LPC17xx
Note that the -L search path is missing from the command line.
The Debug configuration is set up the same way but it correctly generates the -L path in the command line and builds correctly. I can't seem to make the Release build do the right thing.
Any ideas? I'm using LPCXpresso 4.30. I tried upgrading to version 5 hoping to fix this but the LPC-Link debugging was less reliable.
