arm-elf-gcc

[mschneider]

When i try to compile my normal build i am presented with WARNING: arm-elf-gcc is not in your path. When i try to compile i get a bunch of "Dr. Watson" errors. Are these linked to that or am i doing something wrong? or should i just continue?

I have re-installed and added the compiler to the path.

If you added it to your path, type "which arm-elf-gcc" to make sure its actually in the path variable correctly.

Also, dr.watson errors usually mean a windows program crashed I think.  So you're having cygwin crash on you when you try and make?  that doesn't sound right at all.

[mschneider]

No cygwin doesnt crash. And i actually get a zip file (make zip). Everything seems to be working...

On the wiki simple guide to compiling it explains how to put it in your path.  Basically you can either modify your bash profile or edit your path in your environment variables to add that.

This worked for me in an equivalent circumstance, where the m68k file could not be found:

Edit the .bash_profile file in your home directory (cygwin\home\[your name]\.bash_profile), to include the path line at top,

PATH=/opt/m68k/bin:${PATH}

Use Notepad++ or a similar code editor to edit the file (seemingly NOT Windows WordPad or NotePad, which add in line endings).  Notepad++ is freely available (for free) on the web.

Presumably, here for you, you would add the path line to the .bash_profile file,

PATH=/opt/arm/bin:${PATH}

As it was explained in a thread here, the path line change can be added into a different file, as noted in the Rockbox Cygwin install instructions, but that file would get overwritten with a new Cygwin version install; the solution here, recommended in the forums, is said to avoid that issue.

I hope this helps.

well i've added it to my path using "export PATH=/opt/arm/bin:$PATH" and presumably this adds it. but when i try to compile a normal build i get this message over and over (about five or ten times):

C:\cygwin\opt\arm\bin\arm-elf-gcc.exe (2076): *** system shared memory version m
ismatch detected - 0x2D1E009C/0x75BE0081.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

and afterwards i get the normal "WARNING: the compiler you must use is not in your path..."

[elborak]

So have you searched to see if you have multiple cygwin1.dll files in your path?

[mschneider]

Yes i have the current  located in C:/cygwin/bin. it is in my path as :/bin:
I've done a search and the only other cygwin.dll's are in a couple video converters i have. (those are not in my path)

[elborak]

Either you have a bad cygwin install or you have another version of cygwin1.dll that's being picked up. Did you reboot as the message recommended?

[mschneider]

yes, nothing changed.

[saratoga]

Edit your cygwin PATH to remove all paths beginning with C:.

[mschneider]

should i edit with nano? if so, how? I'm not very familiar with using that and all the wiki says about it is to use it.

[Mikerman]

I use Notepad++ (obtained on the web) and find it entirely easy to use.

[mschneider]

How exactly do i edit my PATH though. Do i open a file?

I just do 'echo $PATH' and 'export PATH=/home/linus/sh1/bin:$PATH' steps, though in this case you won't want to export the $PATH variable, just parts of it you get from echo $PATH.

There might be an easier way.
