Would you please explain how to do that?

gdenton could you be more precisse, where is your bottleneck. Your question is too wide.
For guidelines, follow the Wiki for building deviation, on Ubuntu (linux) use the legacy build link.

Thanks for the reply daniel.

On a Windows 10 pc, I updated the compiler, libopencm3 and all deviationtx files, I am able to build devo6 and devo10 files fine.

But when I try to build devo7e I get the following error:

+ Compiling 'pages/128x64x1/advanced/mixer_setup.c'
 + Building 'devo7e.elf'
c:/mingw/stm32/bin/../lib/gcc/arm-none-eabi/8.2.1/../../../../arm-none-eabi/bin/ld.exe: C:\Users\Owner\AppData\Local\Temp\ccICx6q0debugobjtem: file not recognized: file truncated
collect2.exe: error: ld returned 1 exit status
lto-wrapper.exe: fatal error: C:\MinGW\stm32\bin\arm-none-eabi-gcc.exe returned 1 exit status
compilation terminated.
c:/mingw/stm32/bin/../lib/gcc/arm-none-eabi/8.2.1/../../../../arm-none-eabi/bin/ld.exe: error: lto-wrapper failed
collect2.exe: error: ld returned 1 exit status
make: *** [devo7e.elf] Error 1

EDIT:
I found several references to this same type of error on other sites, they think it's a bug with the 8.x compiler on Windows related to "-flto" link-time optimization.
I disabled this in "deviation\src\target\tx\devo\common\Makefile.inc" by commenting out lines 65-68,70 and the devo7e build then succeeded.

Any input would be greatly appreciated.

I gave up on the Windows compiler bug I described in the previous post.
I bit the bullet and installed Ubuntu, new compiler,etc...
I got the build going, I don't see the error when building for the devo7e anymore but I do see the following error on the 3 tx's I've tried:

 + Copying template files for devo10
 + Checking string list length for devo10
ERROR:root:Found unparsable diff in src/libopencm3: @@ -1 +1 @@
  adding: devo10.elf (deflated 66%)

then finishes the build

Is this anything to worry about?
Is anyone seeing this same error?
