1. Error compiling to C

Hi,

I'm running version 3.1.1 on Linux 64 bit.

$ ecu eratosthenes2.eu  
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. 
 
3 .c files were created. 
To build your executable file, type: ./emake 
 
 
$ ls 
emake 
eratosthenes2.c 
eratosthenes2.eu 
init-.c 
main-.c 
main-.h 
 
$ ./emake  
compiling with GNU C 
main-.c 
main-.c: In function main: 
main-.c:35:5: error: implicit declaration of function DeRef1; did you mean DeRef5? [-Wimplicit-function-declaration] 
   35 |     DeRef1(_1t0); 
      |     ^~~~~~ 
      |     DeRef5 
eratosthenes2.c 
init-.c 
linking 
/usr/bin/ld: cannot find main-.o: No such file or directory 
collect2: error: ld returned 1 exit status 
you can now execute: ./eratosthenes2 
 
$ ls ./eratosthenes2 
ls: cannot access './eratosthenes2': No such file or directory 
 

How can I solve this?

The first error was from ld.so, not Euphoria.

libgtk3-nocsd.so.0 was a hack added to prevent the GTK developers from messing with the native look and feel of the window managers on various platforms. It's no longer included in modern linux distros.

You could look for lines in your .bashrc, bash/.bashrc, or .bash_profile files which reference libgtk3-nocds.so, and comment them out. Why they would exist in your bash files is a different question.

However, that's still no guarantee that your Eu 3.1 program will compile on 64-bit machines. See my other post, where I tried to do exactly that. Perhaps with some compile flags, it will work, but that's beyond my pay grade.

Since no one is maintaining Eu 3 anymore for many years, it would make much more sense to use Eu 4, which will compile the program correctly. See my other post in "Errors running script".

I get the same error with EU 4.1 but it compiles with eu.cfg configured for EU 4.2. I don't know what kind of mix it does, calling EU 4.1's euc while having eu.cfg set to EU 4.2, but it works!

4.2 has not been released. For an outsider, euc should work with the stable release.
