I have tried the Window pathname suggestions, with no real success.
I've decided to eliminate this as a variable, so I have switched to
try to build FFmpeg libs under Linux(Ubuntu 17.10). This is the
exact process that I have followed so far: <br>
<div class="moz-forward-container"><b> <br>
</b>1: I have downloaded and decompressed ffmpeg v4.0.2 into
ffmpeg source root directory.<br>
2: I have downloaded and installed Pre-buil2 GNU toolchain forArm
Cortex-M for Linux (gcc-arm-none-eabi-7-2018-q2 update-linux)<br>
from Arm website: <a class="moz-txt-link-freetext"
href="https://developer.arm.com/open-source/gnu-toolchain/gnu-rm"
moz-do-not-send="true">https://developer.arm.com/open-source/gnu-toolchain/gnu-rm</a><br>
3: from cli, I set working directory to ffmpeg source root
directory. ( I created a simple helloworld.c program in working
directory, to test compiler)<br>
4: from cli, I verified arm compiler did successfully create
expected object file for helloworld.c test.<br>
5: from cli, I ran cofigure shell script:<br>
<span>$ ./configure --enable-cross-compile
--cc=/home/ed/Project/armCrossCompile gcc-arm-none-eabi-</span><span>eabi-gcc
--target-os=none arch=arm <br>
6: This is the returned error message:
<br>
<font color="#ff0000"><font color="#3333ff">/home/ed/Project/armCrossCompile/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-gcc</font>
is unable to create an executable file. </font></span><font
color="#ff0000"><span>C compiler test failed.</span></font><span>
<br>
<br>
I have attached zipped log file to show any possible clues. I
won't be able to do too much more today. I will start Monday
morning trying to understand what the log file is showing and
what I might be missing. Again, any advice is appreciated.<br>
<br>
Thanks,<br>
Ed</span>

Try forward slashes, backward slashes for weird character, and
no colon. That is:<br>
<br>
/C/Program\ Files\ \(x86\)/..etc..<br>

It being windows and all. I have much better success cross
compiling ( even for windows native) on Linux. <br>
