CodeBlocks can't find #include <Random.h>
« on: August 08, 2017, 09:19:53 am »
Hello,

in my Header I have #include <Random.h>
in my "Settings" > "Compiler" >
I have:

 "Custom variables"
BOOSTINCLUDE = C:/MinGW/boost/include/boost
BOOSTVARIANTE = -mgw-mt
BOOSTLIBDIR = C:\MinGW\boost\lib

"Linker Settings"
boost_system$(BOOSTVARIANTE)
boost_filesystem$(BOOSTVARIANTE)

"Search directories"
"Compiler"
%USERPROFILE%\Documents\cppbuch\include
$(BOOSTVARIANTE)

"Linker"
$(BOOSTLIBDIR)

But when compiling it says:
fatal error. Random.h: No such file or Directory
=== Build failed: 1 error(s), 0 warning(s)     ...and so on

Can anybody please help ?

Greatings

If random is a boost header you have two errors:
1. C:/MinGW/boost/include/boost should be C:/MinGW/boost/include
2. the include should be <boost/random.h>

Hello oBFusCATed ,

thanks, but that did not work.
I've got the code from a book's Website, which's test programms all worked up to now (when not using boost or any random method).

Any idea ?

Do you have boost? Not all MingW distros have integrated boost.

If you have boost, locate random.h and use the path in Search directories -> Compiler (leave the custom variable step for a second stage). As Obfuscated said, you should remove the last "boost" from the path and use #incude "boost/random.h".

The name of the include file is random.h, not Random.h; in Windows this is not an issue, but if you want code portability you should use the correct name from start.

Hello Miguel,

1.) I have boost
2.) I removed the last "boost" from "Custom variables" Setting so now it says
BOOSTINCLUDE = C:/MinGW/boost/include
BOOSTVARIANTE = -mgw-mt
BOOSTLIBDIR = C/MinGW/boost/lib
Although it made sense to me to have the final "boost" here, because when installing the MinGW
I got the boost-stuff in the directories:
C:/MinGW/boost/lib
and
C:/MinGW/boost/include/boost/boost
WHICH (three times boost !?) looks redundant or weired, doesn't it ?

3.) #include <boost/random.h>   did not help

Did you edit Search directories -> Compiler? The content you posted didn't have the BOOSTINCLUDE variable. Add C:/MinGW/boost/include/boost to search directories and test again; when you get it working do the conversion to a custom variable.

Hello Miguel,

yes, I  edited the  Search directories -> Compiler and I have the BOOSTINCLUDE variable.
I tried your idea >>>
Add C:/MinGW/boost/include/boost to search directories and test again....

It does not work !
I've got to go now, but I will continue on that Problem tomorrow and then I can send you all the configurations of mine...
Thanks, perhaps Hearing of you tomorrow

Boost document and their example seems to indicate that you don't include random.h but one or more of random engine .hpp headers in this list:

In fact random.h does not exist, the correct name is random.hpp
