Thread: Compile in cpp option

hello,

i'm trying compile c++ program in ubuntu. reading "the linux development book". says there gcc options such as:

-x c (lowercase c) c language selection
-x c++ c++ file
-x objective-c objective c
-x assembler assembler file
-x f77 fortran file
-x java java language file


getting errors using "gcc testcpp.cpp -x c++ -o test" , or "gcc testcpp.cpp -o test".

/tmp/ccyt4gjm.o.eh_frame+0x12): undefined reference `__gxx_personality_v0'
collect2: ld returned 1 exit status

guess these options don't apply ubuntu?? there better reference book ubuntu programming?

to compile c++ it's preferable explicitly invoke g++ rather gcc

code:

g++ testcpp.cpp -o test

if wanted compile c++ gcc @ minimum need specify stdc++ library:

code:

gcc testcpp.cpp -o test -lstdc++

afaik -x option used tell compiler language source file contains - redundant if using .cpp suffix. example if had c++ source file called test.txt then:

code:

/documents/forums$ gcc test.txt -o test -lstdc++ test.txt: file not recognized: file format not recognized collect2: ld returned 1 exit status /documents/forums$  /documents/forums$ gcc -x c++ test.txt -o test -lstdc++ /documents/forums$  /documents/forums$ ./test hello world! /documents/forums$

you can check manual page command line options

code:

man gcc
