Hi,
Thank you for the hints:

Building WSJTX on the target system using the build tools as installed via “yum
install ….”
or as a normal user? would for packages for the distro.
- I seem to be making the incorrect assumption that installing a package like
the compiler
would also set the paths needed to use it?

No, installed via sudo yum groupinstall “Development Tools”
>

No, no build has been made yet.

Not moved, the blog entry lists the progression of tools installed (pasted
below)

Not moved.
According to Gregs suggestion
whereis cc1
cc1:
Its not found.
finding it from the root with find . -name cc1 -print
gives
./usr/libexec/gcc/armv7hl-redhat-linux-gnueabi/4.9.2/cc1
making a symlink (surely the compiler package should of done this?)
$ ls -la cc1
lrwxrwxrwx 1 root root 55 Mar 17 21:44 cc1 ->
/usr/libexec/gcc/armv7hl-redhat-linux-gnueabi/4.9.2/cc1
Installed Packages
gcc.armv7hl 4.9.2-6.fc21
@updates
gcc-c++.armv7hl 4.9.2-6.fc21
@updates
gcc-gfortran.armv7hl 4.9.2-6.fc21
./configure still reports
configure: error: C compiler cannot create executables
From the blog:-
build-essentials is “Development Tools” in Fedora land.
$ sudo yum groupinstall “Development Tools”
$ sudo yum install automake autoconf asciidoc texinfo
We also need gfortran, and the libfftw libs.
Trying to install gfortran on its own gave an error, its
$ sudo yum install gcc-gfortran
next up, libtool, fftw-
$ sudo yum install libtool
$ sudo yum install fftw.armv7h fftw-devel.armv7hl
Lets try hamlib.
$ cd .. (to external-source)
$ mkdir hamlib-prefix
$ cd hamlib-prefix
$ git clone git://git.code.sf.net/u/bsomervi/hamlib src
$ cd src
$ git checkout integration (not sure this is needed?)
../src/autogen.sh –prefix=/home/lab/external-source/hamlib-prefix
–disable-shared –enable-static –without-cxx-binding –disable-winradio
CFLAGS=”-fdata-sections -ffunction-sections” LDFLAGS=”-W1,–gc-sections”
checking whether the C compiler works… no

Mike.
