c11 didn't really become available until gcc 4.7.

What versions are those systems running?  gcc --version (just need the version, not all of the output, thanks.)

My C9 instance report 4.4.7.

Windows 7 output works fine. Lots of warnings however. Just copy what is listed in tiny size and paste in text editor, will be correct size then.

Charles,

I'm working on getting the modified version of your code working on C9 and Red Hat is complaining on the run but not the compile.

allbasic@c_basic:~/668428/usr/john/cbc $ ./t_cbc
./t_cbc: error while loading shared libraries: __vdso_time: invalid mode for dlopen(): Invalid argument
allbasic@c_basic:~/668428/usr/john/cbc $

The same code runs fine on Ubuntu 64 bit.

John

I posted the same problem on c9 Blog a few days ago. From what I read, it is having conflicting versions of the same libs.

Charles only posted the his code here today so I'm not sure what you're saying.

I was able to get all the .c source files fixed so CINT could run Charles new update. This is what CINT is saying ...

Something very strange is going on with C9. I'm getting the same error with my C BASIC simple demo. This compiled fine before. CINT isn't having a problem with it. ???

Code: [Select]
allbasic@c_basic:~/668428/usr/john/cintbasic $ ./cb
./cb: error while loading shared libraries: __vdso_time: invalid mode for dlopen(): Invalid argument
allbasic@c_basic:~/668428/usr/john/cintbasic $

The All BASIC C9 workspace is hosed. I went to another workspace and my cb.c example compile with gcc. I then tried Charles new class example.

Code: [Select]
scriptbasic@c9basic:~/642383/cbasic $ gcc Test.c -o teat1
In file included from BasicClassLibrary.h:9,
                 from Test.c:3:
StringClass.c:878: error: redefinition of typedef ‘StringClassTable’
StringClass.c:4: note: previous declaration of ‘StringClassTable’ was here
StringClass.c:878: error: redefinition of typedef ‘StringMethods’
StringClass.c:4: note: previous declaration of ‘StringMethods’ was here
scriptbasic@c9basic:~/642383/cbasic $ ./cb
1
2
3
4
5
x is now 6
My guess is 6
6
Double it up
scriptbasic@c9basic:~/642383/cbasic $

I tried both cb.c and Test.c on WinXP (VirtualBox) with MinGW32 (gcc version 4.7.1 (tdm-1)) and it worked without issue.



Here is CINT under WinXP.

Thank you all for testing :)

I believe most of the problems are with line 4 in StringClass:

typedef struct StringClassTableStruct StringClassTable,*StringMethods;


It is a forward declaration for the ClassTable structure, which is defined following all the methods

I am using GCC 4.7.0

If this kind of declaration is unsupported by other versions of C then there is a compromise: make the String methods (void*) / ref

 class StringClassStruct
  begin
//BASE MEMBERS
  ref f;           // pointer to methods table
  int type;     // dynamic type code
  int offset;        // size of this header
  int nbytes;      // buffer ze for body of data
  int count;        // number of elements
  int size;           // size of each element
  end
  StringClass,*StringObject;


This compromises OOP notation, but its not serious, since it is generally more efficient to to work with dreferenced methods.

    ((StringMethods)vo->f)->Show(&vo); //ugh!

    dim as StringMethods f=vo->f; //methods

    f->SetChars(&uo,"LO");
...


I've update the zip here:

Not there yet.

Can you try altering the first 2 offending lines in test.c

  //((StringMethods)vo->f)->Show(&vo); //ugh!

    dim as StringMethods f=(StringMethods) vo->f; //methods

Okay, I made the change.


    // dim as StringMethods f=vo->f; //methods
    dim as StringMethods f=(StringMethods) vo->f; //methods

Code: [Select]
scriptbasic@c9basic:~/642383/cbclass $ gcc Test.c -o test
Test.c: In function ‘TestStrings’:
Test.c:14: warning: dereferencing ‘void *’ pointer
Test.c:14: error: request for member ‘Show’ in something not a structure or union
Test.c:15: warning: dereferencing ‘void *’ pointer
Test.c:15: error: request for member ‘SetChars’ in something not a structure or union
Test.c:16: warning: dereferencing ‘void *’ pointer
Test.c:16: error: request for member ‘SetChars’ in something not a structure or union
scriptbasic@c9basic:~/642383/cbclass $

I don't think that changed anything.

I'm on chat if that would speed things along. (I'm fading fast 2:45 am here)

I posted them here.

If works fine on Ubuntu. Only Red Hat / CentOS are complaining. AIR is having issue on OSX.

No further ideas here. Sleep well!

Does MacOsx or RedHat have problems with CRLF  (ascii 13,10) line formats?
