- If you are using AT as directed by an IBM product team (ex.: IBM XL Compiler or PowerVM Lx86) please report suspected AT problems to IBM Support using that product name and entitlement.
- IBM's Support Line for Linux Offering in the United States now provides support for AT as well. If you have a contract with a U.S. Support Line for Linux contract, place a call to IBM Support:
- Dial 1-800-426-IBM-SERV
- Option #2 (Other business products or solutions)
- Option #2 (Software)
- Option #7 (Other OS/Linux)
- All other users can use an electronic forum that is monitored Monday through Friday. For questions regarding the use of or to report a suspected defect in AT, click here.
- Log in.
- Start a topic.
- Enter and save your question or problem.
- An initial response will be attempted within 2 business days.
Installation
The gpg public key gpg-pubkey-6976a827-5164221b will be provided in the repository where these release notes were found. This pubkey can be used to verify the authenticity of both the Advance Toolchain rpms and the repository contents.
Download this gpg-pubkey and import it into your rpm database using the following:
rpm --import gpg-pubkey-6976a827-5164221b
Using YUM
First, if you have never created an Advance Toolchain repository configuration file, you need to do so. Create the following file using the text editor of your choice as root:
/etc/yum.repos.d/at7.0.repo
and add the following content:
# Begin of configuration file
[at7.0]
name=Advance Toolchain Unicamp FTP
baseurl=ftp://ftp.unicamp.br/pub/linuxpatch/toolchain/at/redhat/RHEL6
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=ftp://ftp.unicamp.br/pub/linuxpatch/toolchain/at/redhat/RHEL6/gpg-pubkey-6976a827-5164221b
ftp://ftp.unicamp.br/pub/linuxpatch/toolchain/at/redhat/RHEL6/gpg-pubkey-3052930d-5175955a
# End of configuration file
To install execute yum install as root:
yum install advance-toolchain-at7.0-runtime
yum install advance-toolchain-at7.0-devel
yum install advance-toolchain-at7.0-perf
Answer y when YUM prompts for confirmation.
Manual installation
If you are installing the rpms manually you will need to install them in the following order (due to prerequisites):
advance-toolchain-at7.0-runtime-7.0-4
advance-toolchain-at7.0-devel-7.0-4
advance-toolchain-at7.0-perf-7.0-4
advance-toolchain-at7.0-mcore-libs-7.0-4
advance-toolchain-at7.0-runtime-at6.0-compat-7.0-4
If you are updating a previous installation, you need to update as a batch, so rpm can solve the dependencies, i.e.:
rpm -Uvh advance-toolchain-at7.0-runtime-7.0-4.ppc64.rpm \
advance-toolchain-at7.0-devel-7.0-4.ppc64.rpm \
advance-toolchain-at7.0-perf-7.0-4.ppc64.rpm \
advance-toolchain-at7.0-mcore-7.0-4.ppc64.rpm \
advance-toolchain-at7.0-runtime-at6.0-compat-7.0-4.ppc64.rpm
The rpm command should always be run as root. Failure to do so will result in an error similar to this:
error: can't create transaction lock on /var/lib/rpm/__db.000
Important notes
- Timezone files: If you need to use something different than Factory, then you should copy the timezone file you want from /opt/at7.0/share/zoneinfo to /opt/at7.0/etc/localtime
- advance-toolchain-at7.0-runtime-compat-7.0-4: DO NOT INSTALL it on SLES10 and beyond or RHEL5 and beyond. These are intended for runtime compatibility on SLES9 and RHEL4 only (see below).
Installation on SLES9 and RHEL4 - Runtime compatibility
Users running applications on SLES9 or RHEL4 may install the compatibility rpm advance-toolchain-at7.0-runtime-compat-7.0-4 in order to get the Advance Toolchain runtime libraries.
Installation of the cross-compiler (Intel x86)
You can download advance-toolchain-at7.0-cross-7.0-4 and install in a x86 machine to build Power binaries on it. Binaries generated by the cross-compiler will run on a Power system with the same version of the Advance Toolchain installed.
