<pre wrap="">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:
*
*1: I have downloaded and decompressed ffmpeg v4.0.2 into ffmpeg source
root directory.
2: I have downloaded and installed Pre-buil2 GNU toolchain forArm
Cortex-M for Linux (gcc-arm-none-eabi-7-2018-q2 update-linux)
from Arm website:
<a class="moz-txt-link-freetext" href="https://developer.arm.com/open-source/gnu-toolchain/gnu-rm">https://developer.arm.com/open-source/gnu-toolchain/gnu-rm</a>
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)
4: from cli, I verified arm compiler did successfully create expected
object file for helloworld.c test.
5: from cli, I ran cofigure shell script:
$ ./configure --enable-cross-compile
--cc=/home/ed/Project/armCrossCompile gcc-arm-none-eabi-eabi-gcc
--target-os=none arch=arm
</pre>

<pre wrap="">
(There is something wrong with the "arch" option, both here and in the log.)
Should probably be:
./configure --cross-prefix=/home/ed/Project/armCrossCompile
gcc-arm-none-eabi-eabi-
--target-os=none --arch=arm
</pre>
</blockquote>
<font color="#3333ff">I've run configure exactly as shown above.
The results were the same as previous run. <br>
I've attached config.log file.</font><br>

<pre wrap="">6: This is the returned error message:
/home/ed/Project/armCrossCompile/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-gcc
is unable to create an executable file. C compiler test failed.
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.

<pre wrap="">
Please do not compress the log, please avoid top-posting here.
If it still fails, try to compile FFmpeg's test program ("int
main(void){ return 0; }")
with the options FFmpeg uses ("-march=armv4t") and find out if it
really succeeds
from cli.</pre>

<font color="#3333ff">I wasn't exactly sure I understood this step.
So I created a simple C test file with<br>
int main(void) { return 0; }<br>
<br>
I then ran cross compiler from cli with the FFmpeg option:<br>
$
/home/ed/Project/armCrossCompile/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-gcc
-c -march=armv4t test.c<br>
<br>
the object file was created successfully. Please let me know If I
should run some additional test(s).</font><br>
