मैं पहले से ही अपने सिस्टम में 4.4.7 gcc था। मेरा सिस्टम आरएचईएल 6.6 है।
[root@gksrv Desktop]# gcc --version

मैं gcc-4.8.2 में अपग्रेड करना चाहता हूं और मैं इसे अपने सिस्टम पर इंस्टॉल करने के सभी चरणों से गुजरा।
टाइपिंग के बाद मुझे प्राप्त आउटपुट का अंतिम भाग make install
निम्नानुसार है:
Libraries have been installed in:
/root/gcc-4.8.2/lib/../lib64
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

हालाँकि, gcc -v टाइप करने के बाद मैंने पाया कि कंपाइलर को जगह नहीं मिली:

मैंने रूट को रूट के रूप में सेट करने की कोशिश की। मैंने टाइप किया vim .bashrc
और मैं इस विंडो पर आया:
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
if [ -d "/opt/intel/Compiler/11.0/083/bin" ] ; then
PATH="/opt/intel/Compiler/11.0/083/bin:$PATH"
fi
export ALTERAOCLSDKROOT="/home/altera/15.0/hld"
export QSYS_ROOTDIR="/home/altera/15.0/quartus/sopc_builder/bin"
PATH= /root/gcc-4.8.2/bin:$PATH
export PATH
जैसा कि ऊपर देखा जा सकता है, मैंने इस स्क्रिप्ट में निम्नलिखित तरीके से रास्ता जोड़ा:
PATH= /root/gcc-4.8.2/bin:$PATH
export PATH
टाइप करने के बाद मुझे echo $PATH
निम्न प्रतिक्रिया मिलती है:
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-1.b13.el6.x86_64/bin:/usr/lib64/qt-3.3/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-1.b13.el6.x86_64/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/apache/apache-ant-1.9.9/bin:/root/bin:/usr/apache/apache-ant-1.9.9/bin
Gcc-4.8.2 के लिए पथ का स्पष्ट रूप से पता नहीं चला है।
मैं PATH को कैसे सेट कर सकता हूं ताकि gcc-4.8.2
डिफ़ॉल्ट कंपाइलर के रूप में पहचाना जाए और नहीं gcc-4.4.7
?
संपादित करें:
मैंने बॉक्समा की सलाह का पालन किया और मेरा मार्ग अद्यतन हो गया:
/root/gcc-4.8.2/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-1.b13.el6.x86_64/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-1.b13.el6.x86_64/bin:/usr/lib64/qt-3.3/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-1.b13.el6.x86_64/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/apache/apache-ant-1.9.9/bin:/root/bin:/usr/apache/apache-ant-1.9.9/bin:/usr/apache/apache-ant-1.9.9/bin
टाइप करने के बाद अब मुझे निम्न आउटपुट मिले gcc -v
