ROOT

Dear Experts,

I wanted to install root 5.34/38 version on my ubuntu 18.04 machine with gcc 7.3, below is my problem showing when I trying to install it,
xz-5.0.3/src/liblzma/api -o core/lzma/src/ZipLZMA.o -c /home/arup/root-5.34/root/core/lzma/src/ZipLZMA.c

I am behind the proxy firewall, but I’ve set the username and password on the global gitgub

git config --global http.proxy http://proxyUsername:proxyPassword@proxy.server.com:port

after this also the same problem is coming, can you help me out from this

Hi,

5.34 is an old and unsupported version. Do you have the same problem with 6.16?

Cheers,

I guess you should be able to compile ROOT 5.34/38 thought I would say that you should better take the head of the v5-34-00-patches branch (you may need to add “--enable-gsl-shared --disable-fitsio” when configuring it) for ROOT 5 or the newest ROOT 6 release.

Maybe the problem is that “curl” actually tries to download files using “https”, not “http” (and maybe it is missing an appropriate “proxy”). You need to make sure that the following command works:

curl -L https://github.com/lz4/lz4/archive/v1.7.5.tar.gz > 1.7.5.tar.gz

Yes, you are right, somewhere the proxy is missing, my problem is in which file should I set it?

In case of the following command the same problem arises
curl -L https://github.com/lz4/lz4/archive/v1.7.5.tar.gz > 1.7.5.tar.gz

See the “FILES” and “ENVIRONMENT” sections in the “man curl”.

Thank you very much. After setting the proxy to .curlrc file and adding “–enable-gsl-shared --disable-fitsio” root5.34/38 installed successfully in my machine. Thank you very much for directing
