Very stupid questions :(

Hello, colleagues,

Could someone tell me why CINT throws “Unexpected EOF G__ignorestream():” pointing to the last line of .C file I’m trying to load?

How can I paste text from clipboard to CINT? And vice versa?

Thank you in advance.

You had many C++ mistakes in your code.
You can check the errors using ACLIC.
Instead of
.L GAMMA.C
do
.L GAMMA.C+

I modified your code to work.

Yeah, Ok, I missed those backslashes, thanks for them, and I didn’t actually understand from the first glance, the possibility of adding a + to precompile the macro (if that is what the plus does).

However, the corrected text doesn’t work either. Please forgive me if I just failed to find the necessary info in the manual’s first 9 chapters.

Output as follows.

[color=olive]
root[0] .L brun.C+
Info in TWinNTSystem::ACLiC: creating shared library …\brun_C.dll
’cl’ is not recognized as an internal or external command, operable program or batch file.
… repeated several times …
Error in : Compilation failed!

Thank you for support. Would appreciate further help.

by the way, should we move to ROOT support? it was quite a question for me to select the appropriate branch :wink:
