Install compile errors, application won't successfully start

[rdingham]

when running install.sh, on Raspberry Pi 4, I get a lot of compiler warnings like:

array_range_check.cc:202:36: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] STAGE3_ERROR(0, symbol, symbol, "Subrange has lower limit (%"PRId64") larger than upper limit (%"PRId64").", GET_CVALUE( int64, symbol->lower_limit), GET_CVALUE( int64, symbol->upper_limit)); ^ array_range_check.cc:202:71: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] STAGE3_ERROR(0, symbol, symbol, "Subrange has lower limit (%"PRId64") larger than upper limit (%"PRId64").", GET_CVALUE( int64, symbol->lower_limit), GET_CVALUE( int64, symbol->upper_limit)); ^ array_range_check.cc:212:36: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] STAGE3_ERROR(0, symbol, symbol, "Subrange has lower limit (%"PRIu64") larger than upper limit (%"PRIu64").", GET_CVALUE(uint64, symbol->lower_limit), GET_CVALUE(uint64, symbol->upper_limit)); ^ array_range_check.cc:212:71: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] STAGE3_ERROR(0, symbol, symbol, "Subrange has lower limit (%"PRIu64") larger than upper limit (%"PRIu64").", GET_CVALUE(uint64, symbol->lower_limit), GET_CVALUE(uint64, symbol->upper_limit)); ^ ar: u' modifier ignored sinceD' is the default (see U') Making all in stage4 Making all in generate_c In file included from generate_c.cc:525: generate_c_il.cc: In member function ‘virtual void* generate_c_il_c::visit(il_function_call_c*)’: generate_c_il.cc:957:11: warning: this ‘if’ clause does not guard...

When I try to run OpenPLC Editor I get:

No module named 'lxml'

That’s because the editor was never meant to be run on a Pi. It should run on your desktop. Now, if you can figure out a way to install lxml on the Pi then it might work

It looks like you should be able to install lxml on the pi, not sure if this will enable you to run the editor though. Stack Exchange Link

sudo apt-get install python3-lxml python-lxml

sudo apt-get install libxml2-dev libxslt-dev python-dev

pip install lxml --user
