#69 Linker fails with space in path to linker script file

[Erich Styger]

I'm using the GNU ARM Eclipse plugins Version 1.1.7-201312221905 with Windows7 64bit and Eclipse Kepler.

I faced a problem with a path to the linker file using spaces (linker -T option).
My project is in
C:\ProgramData\Processor Expert\CWMCU_PE5_00\Examples\FRDM-KL25Z\FRDM-KL25Z_GNU_Arm_Eclipse
(note the space between "Processor" and "Expert")

I tried to double quote the path in the linker settings (Project > Properties > C/C++ Build > Settings > Cross ARM C Linker > General > Script Files (-T):
"${ProjDirPath}/linker/MKL25Z128_flash.ld"
but this did not help (the plugin removes the double quotes? See console output below:

thank you for the report, I'll investigate it as soon as possible.

it must be similar to the other one (as it seems, using Macs for development has disadvantages too...)

[Liviu Ionescu (ilg)]

the problem was related to the order of operations, the macro substitution was performed after the whitespace quoting, and the substituted paths remained unquoted.

I added the macro substitution call before the whitespace quoting and on OS X the problem seems solved.

please check on Windows and confirm.

the new version is available from the updates-test site.

I have this specfied:
"${ProjDirPath}/linker/MKL25Z128_flash.ld"
but this gave me this (error):

'Building target: FRDM-KL25Z_GNU_Arm_Eclipse.elf'

So I see it escapes the space with Processor\ Expert, but still fails (because not quoted).
Removing the double quotes was the same.

So still something is missing?

[Liviu Ionescu (ilg)]

hmmm, it looks like the windows make program does not process '\ ' properly and it really needs double quoting.

a new version is available from the updates-test site; I tried it on a virtual machine and it seems to work with the make borrowed from the code sourcery distribution.

Hi Liviu,
good news: now it works :-)
