Debug is OK, Release

Hopefully a simple one for someone to answer, but I'm stumped!

Using the 1768 xpresso board, I have been running in debug configuration for a while and all is fine.

I'm now (unsucessfully) trying to use the CAN port, and I think one problem I have might be the clock speeds, so I change the PLL0CFG_Val and CCLKCFG_Val (I'm using CMSIS), but the clock value doesn't change.

I then think that this may be because I'm in debug mode (where a crystal clock doesn't mean much when single-stepping), so I right-click on the project and choose 'build configurations -> set active -> release'.

When I build the project now, I get the following error from the linker:

[SIZE=2][FONT=Courier New]Invoking: MCU Linker
arm-none-eabi-gcc -nostdlib -L"" -Xlinker -Map=Mike1768CAN.map -Xlinker --gc-sections -mcpu=cortex-m3 -mthumb -T "Mike1768CAN_Release.ld" -o"Mike1768CAN.axf" ./src/IRQ.o ./src/VSM.o ./src/can.o ./src/cr_startup_lpc17.o ./src/main.o -lCMSISv1p30_LPC17xx

collect2: ld returned 1 exit status
arm-none-eabi-gcc.exe: unrecognized option '-Map=Mike1768CAN.map'
make: *** [Mike1768CAN.axf] Error 1[/FONT][/SIZE]

What am I missing? The [SIZE=2][FONT=Courier New]CMSISv1p30_LPC17xx [/FONT][/SIZE]file is where it's always been ;-)
How can the same code compile, link, download and run in 'debug' configuration but not in 'release'?

Any help at all would be appreciated.
Mike

You have to compile also a 'Release' version of CMSISv1p30_LPC17xx. Obviously this Lib cannot be found.

As per Zero's response, if you build a project for release, you need to make sure that you have also built a release build of the CMSIS library (or any other library projects that your project is linked with).

The easiest way to make sure this happens is to change the build configuration of both projects (or perhaps all projects in your workspace) at the same time. For details of how to do this, see the FAQ:

Thank you both for your quick and helpful replies.
The answer is obvious when someone points it out to you ;-)

Cheers!
