Incomprehensible line numbers in error / warning messages

ROOT
1

Hi,

When running cint macros using loops with blocks in curled brackets the line numbering in my root installataion is somehow incomprehensible. The line numbers indicated in the error/warning output of cint do not correspond with the actual line numbering in the source file. And i did not find any hint on this in the documentation until now.

The following code sample illustrates this effect.

int TEST ()
{

for (int i = 0; i < 4; i++){
printf(“Hello1\n”);
printf(“Hello2\n”);
};

ERROR ();

return 10;
};

if runing that bit of code in my installation I get the following output.

root [1] .x TEST.C
Hello1
Hello2
Hello1
Hello2
Hello1
Hello2
Hello1
Hello2
Error: Function ERROR() is not defined in current scope TEST.C:11:
*** Interpreter error recovered ***

Here the error line number is given with 11 but the undefined function ERROR is located in line 9. After some tests i got the impression that the scope of the for-loop indicated by the curly brackets seems to confuse cint in some way.

I am interested if i made a mistake in the installation and if so how to fix it.

Thanks

Hi,

The error message issued by CINT are known to be sometimes somewhat inaccurate and/or hard to decipher. We do plan on improving the situation.
We are currently working on revamping the CINT code base when this is done (hopefully soon) we would be in a better position to address those kind of issues).

In the meantime, whenever seeing a ‘weird’ CINT error message, I recommend to ask the compiler for a better diagnosis by simply using ACLiC:root [2] .L TEST.C+ Info in <ACLiC>: script has already been loaded in interpreted mode Info in <ACLiC>: unloading /var/tmp/./TEST.C and compiling it Info in <TUnixSystem::ACLiC>: creating shared library /var/tmp/./TEST_C.so /var/tmp/./TEST.C: In function 'int TEST()': /var/tmp/./TEST.C:9: error: 'ERROR' was not declared in this scope g++: /var/tmp/./fileo6gfB0.o: No such file or directory Error in <ACLiC>: Compilation failed!
