Hi there
I apologize for posting this again as I was not subscribed to the mailing list on posting my first message, so if the first message made to the list without me being a subscriber, I apologize.
I added some more info as to my issue below.
I need to cross-compile an application written in C for ARM v8 (aarch64) and found the toolchain on your website.
I am running Windows 10 using Cygwin 32-bit as I am already compiling for arm6, arm7 and Linux (x86 and x64) successfully.
I downloaded https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-elf... and deployed it into my Cygwin installation with no issues.
When I ran my script, I get the following error message: aarch64-elf-gcc.exe: error: CreateProcess: No such file or directory
I enabled verbose mode on the GCC and the result is below. My Cygwin's default GCC version is 4.8.3, but I am running 7.2.1 for this. I also tried 4.9.4 as well using a different Cygwin instance.
Can you please advise how I can get around this error? I am able to cross-compile using the 100% exact script with all other architectures with the only difference being the toolchain and architecture.
I also found references to C:\cygwin\bin in the logs (note the backslashes instead of forward slashes) below which I'd imagine would cause the issue I am experiencing as I have no way to alter the -iprefix in the COLLECT_GCC_OPTIONS as I am not setting this parameter - seems the GCC compiler is injecting this in.
I also realised that I needed to use the linux-gnu version of the toolchain and not the ELF version which I did, but got the same results.
Cygwin DLL version (just in case).
I called: cygcheck -p cygwin1.dll |grep "cygwin:"
And it returned:
cygwin-2.10.0-1 - cygwin: The UNIX emulation engine cygwin-2.8.2-1 - cygwin: The UNIX emulation engine cygwin-2.9.0-3 - cygwin: The UNIX emulation engine
7.2.1
