Experimental Physics and
Industrial Control System

Hi Matt,

 

Yes, there are no compile errors after commenting on these two lines.

My test target CPU is 32-bit.

 

Thank you,

Hi,

 

I don’t have a Ubuntu system to check, but according to this:

https://manpages.ubuntu.com/manpages/focal/en/man3/uint64_t.3avr.html

 

int64_t is ‘long long’

 

And in pywrapper.cpp:

 

template bool PyWrapper::exec(const std::string&, bool, char*);

template bool PyWrapper::exec(const std::string&, bool, int8_t*);

template bool PyWrapper::exec(const std::string&, bool, uint8_t*);

template bool PyWrapper::exec(const std::string&, bool, int16_t*);

template bool PyWrapper::exec(const std::string&, bool, uint16_t*);

template bool PyWrapper::exec(const std::string&, bool, int32_t*);

template bool PyWrapper::exec(const std::string&, bool, uint32_t*);

template bool PyWrapper::exec(const std::string&, bool, int64_t*);

template bool PyWrapper::exec(const std::string&, bool, uint64_t*);

template bool PyWrapper::exec(const std::string&, bool, float*);

template bool PyWrapper::exec(const std::string&, bool, double*);

// These are needed on 64-bit GNU system that defines int64_t as long instead of long long

// Unfortunately this makes the code here not very portable.

template bool PyWrapper::exec(const std::string&, bool, long long*);

template bool PyWrapper::exec(const std::string&, bool, unsigned long long*);

 

So the additional instantiations of ‘long long’ and ‘unsigned long long’ is causing the problem. You could try commenting those last two lines out, and see if that works, since the int64 lines have already been defined.

 

On my RHEL system, int64 is ‘long int’ (aka ‘long’), so it compiles fine.

 

I’m not really a pydevice developer, so I’m not sure of the most portable way forward here, but perhaps we can use the epics typedefs rather than the C/C++ typedefs?

 

Cheers,

Matt

 

 

I am attempting to compile the Klemen’s PyDevice device support and getting compile errors.

Any suggestions?
