"You have to install development tools first" on amzn-ami-hvm-2016.09 when ruby-devel is installed #158

Closed ensslen closed 7 years ago

ensslen commented 7 years ago

"gem install ruby-oci8" is failing on my AWS amzn-ami-hvm-2016.09 linux VMs. Easily reproducable on a fresh VM with nothing but the instant-client unzipped, the paths set, and ruby-devel installed.

Thanks for the help.

  1. Could you run the following commands?

    $ echo "int main { return 0; }" > main.c
$ gcc -o main main.c
$ ./main
$ echo $?
0

    If it fails, you need to install workable C compiler.

  2. If the above command works, could you run the following commands?

    $ echo "int main { return 0; }" > main.c
$ gcc -o main main.c -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -mtune=generic -fPIC -fstack-protector -rdynamic -Wl,-export-dynamic  -m64 -lpthread -lrt -ldl -lcrypt -lm   -lc
$ ./main
$ echo $?
0

    I guess the the second command fails. If the gcc complains that some options are unsupported, remove them until the gcc works.

  3. Fix rbconfig.rb Run the following command to get the directory containing rbconfig.rb.

    $ ruby -r rbconfig -e "p RbConfig::CONFIG['rubyarchdir']"

    Look into rbconfig.rb and erase options which are removed in the previous step.

As @kubo suggested there was no gcc installed. sudo yum install gcc fixed my problem so that gem install ruby-oci8 worked correctly.

Thank you so much for your assistance, and for your software in the first place.
