Hello GiNac-list, I have some problems installing the GiNaC on Linux. May I ask you for advice? I followed the tutorial PDF to install, and the linux computer showed a message that "See check/test-suite.log Please report to ginac-list@ginac.de ". So, I sent an email to get some advice. I have the below prerequisite software version. $ g++ --version : 4.8.5 $ git --version : 1.8.3.1 $ autoconf --version : 2.69 $ libtool --version : 2.4.6 $ automake --version : 1.13.4 These files are in the '/usr/bin/' and I will install the GiNaC in the '/home/{USERNAME}/Package/' (I think these points make some problems.) First, I install the CLN before installing the GiNaC. $ ./configure --prefix=/home/{USERNAME}/Package $ make $ make check (--> all Pass) $ make install And then, I try to install the GiNaC $ export PKG_CONFIG_PATH=/home/{USERNAME}/Package/lib/pkgconfig $ ./configure --prefix=/home/{USERNAME}/Package $ make $ make check (--> there are 7 fail, and 51 PASS; it shows me the above message) Related log file(test-suite.log) is attached, I do not know what is wrong. Please let me help to install GiNaC well Thanks, ljw.
