Re: [CT_NG] crosstool-ng 1.1.0's cpp compile error

[invain <leemgs at gmail dot com>]

I figure out  reason of " error message: C++ compiler not installed on
this system",
When I compile hello cpp source using  arm toolchain that are built
with crosstool-ng
ver 1.1.0.

This reason is  --enable-language=c,${opt} problem  because sed(stream editor)
parsing  is dismatch in centos 5.X distribution.

So, I edited  cc-gcc.sh script file to solve this problem right now.










vi /opt/crosstool-ng-1.1.1/scripts/build/cc-gcc.sh (edit
--enable-languages-c,c++)

--------

     81         --enable-symvers=gnu                        \

     82         --enable-languages=c,c++                    \

     83         --disable-shared                            \

            ............... Middle Omission ............

    131         --enable-symvers=gnu                        \

    132         --enable-languages=c,c++                    \

    133         --enable-shared                             \





--------



and I typed "centos5#> ct-ng build.  I can finished compiling of
tollchain successfully with crosstool-ng 1.1.0.

I can confirm exectuable file

 in /opt/invaindtoolchain110/bin/targets/arm-invaind-linux-gnueabi/build/gcc-core-shared/bin
directory.







[root@centos51 bin]# ls

arm-invaind-linux-gnueabi-ar         arm-invaind-linux-gnueabi-gcj

arm-invaind-linux-gnueabi-as         arm-invaind-linux-gnueabi-gcjh

arm-invaind-linux-gnueabi-gccbug     arm-invaind-linux-gnueabi-strip

[root@centos51 bin]#







And , I write cpp  hello source code.

and then, I compiled  like below.

But, I  meet "  iostream: No such file or directory" error message
when compile cpp source.



[root@centos51 bin]#

[root@centos51 bin]# ./arm-invaind-linux-gnueabi-g++ -o cpphello2.o
/opt/cpphello2.cpp

/opt/cpphello2.cpp:1:20: error: iostream: No such file or directory

/opt/cpphello2.cpp: In function 'int main(int, char**)':

/opt/cpphello2.cpp:4: error: 'cout' was not declared in this scope

/opt/cpphello2.cpp:4: error: 'endl' was not declared in this scope





This is source code.



[root@centos51 bin]#

[root@centos51 bin]# cat /opt/cpphello2.cpp

#include <iostream>

int main( int argc, char **argv )

{

    cout << "Hello World" << endl;

    return 0;

}



[root@centos51 bin]#




Anyone have idea or reason about this problem?

Share me your tech knowledge to solve this problem..
Currently, I think that  header file realted  arrange miss....
