This native extension contains a source library from Peak and comes with pre-compiled native executables for both Classic CAN and FD.

Re-compiling the native extension

You just need to re-compile the native extension if the original native executables do not fit to your system (e.g. library incompatibilities with Linux).

Go to Preferences->impulse->Native Extensions->Peak Can (FD) Bus Native.

• Please check if your system has the required GNU compatible toolchain installed (g++,make)
• Press Make

mkdir -p linux-x86_64
gcc -m64 main.c ../flux.c ../lz4.c ../fastlz.c linux/src/libpcanbasic_legacy.cpp  -I .. -I .   -D FLX_CONTROL -D FLX_COMPRESS -D FLX_STDIO  -O3 -Ilinux -Ilinux/src -Ilinux/src/libpcanfd  -DNO_RT -lm -lpthread    -o linux-x86_64/peakcan
chmod 777 linux-x86_64/peakcan

(similar output for FD)

If the output shows an error, you might need to extend the parameters for additional flags and libraries. If you can not resolve, send an email to This email address is being protected from spambots. You need JavaScript enabled to view it. with the text of the message output field.
