graph tool - proper linking of PATH and LD_LIBRARY_PATH after gcc-5.2 install in own directory -


i compiled , installed gcc-5.2. did not have root access installed in own directory. forget @ end meant link through ld_library_path , path 

setenv ld_library_path /bigbang/data/username/lib/gcc-5.2/lib setenv ld_library_path /bigbang/data/username/lib/gcc-5.2/lib64:$ld_library_path setenv path /bigbang/data/username/lib/gcc-5.2/bin:$path

when run ./gcc following error:

gcc: error while loading shared libraries: libiconv.so.2:

is there wrong how linking lib paths? in advance. also, simple did configure ./configure --prefix=/bigbang/data/username/lib/gcc-5.2/, recommended configuration flags should use? i'm aiming use graph_tool.

if have installed gcc non-standard prefix /my/gcc/prefix can use installation without special preparations passing:

-b/my/gcc/prefix

whenever call frontend (gcc, g++, etc). call frontend usual command:

gcc -b/my/gcc/prefix ...

this assumes some version of gcc installed standardly.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
