Hello, i don't know is this the right place to ask my question. If not, sorry. I have problem installing different packages from source, this due a wierd behaviour of configure script in - you know, the script you must issue before compileing the package. I want all the necessery files to go in /opt directory, so i execute configure with --prefix=/opt. All good, configure runs wiht no problems. But after compilaiton 'make install' fails to copy everything to its right place, under /opt dircetory. After inspecting configure generated Makefile, i've found the problem. To demonstrate what i mean, heres some lines from example Makefile: # Install directories PREFIX= --prefix/opt prefix= --prefix/opt exec_prefix= ${prefix} BINDIR= ${exec_prefix}/bin INST_DIR= ${prefix}/grass5 The PREFIX is defined as --prefix/opt instead /opt. Why is that? Where can i search for source of this problem? Thanks, Priit Voolaid
