Hello!
I want to install toolchain for stm32 microcontrollers.
| Code: | | crossdev -S -t arm-none-eabi |
finished with no errors, but I can't find arm-none-eabi-g++ in installed binaries. Gcc, as, ld... all except g++. What I'm doing wrong? |

I manged to solve this issue. (Apologies for the necro-bump, this was the only thread I found on this issue when trying to find a solution myself).
I noticed in the initial crossdev output that only stage 3 was being built,
| Code: | | * Stage: 3 (C compiler & libc) |
which according to the output of crossdev --help does not build a full compiler:
| Code: | Stage Options:
-s0, --stage0 Build just binutils
-s1, --stage1 Also build a bare C compiler (no C library/
C++/shared GCC libs/C++ exceptions/etc...)
-s2, --stage2 Also build kernel headers
-s3, --stage3 Also build the C library
-s4, --stage4 Also build a full compiler [default]
(shared libs GCC/various lang frontends/etc...) |
I add the -s4 flag to the crossdev command and this built the g++ compiler:
| Code: | # crossdev --stable -t arm-none-eabi -s4
* crossdev version: 20201129
* Host Portage ARCH: amd64
* Host Portage System: x86_64-pc-linux-gnu (i686-pc-linux-gnu x86_64-pc-linux-gnu)
* Target Portage ARCH: arm
* Target System: arm-none-eabi
* Stage: 4 (C/C++ compiler)
...
# ls /usr/bin/arm*g++
/usr/bin/arm-none-eabi-g++ |
