Support
Customer support for the Advance Toolchain (AT) is provided in one of three ways:
- 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
Manual installation for rpms
If you are installing the rpms manually you will need to install them in the following order (due to prerequisites):
advance-toolchain-at9.0-runtime-9.0-2 advance-toolchain-at9.0-devel-9.0-2 advance-toolchain-at9.0-perf-9.0-2 advance-toolchain-at9.0-mcore-libs-9.0-2 advance-toolchain-at9.0-runtime-at8.0-compat-9.0-2
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-at9.0-runtime-9.0-2.ppc64.rpm \ advance-toolchain-at9.0-devel-9.0-2.ppc64.rpm \ advance-toolchain-at9.0-perf-9.0-2.ppc64.rpm \ advance-toolchain-at9.0-mcore-9.0-2.ppc64.rpm \ advance-toolchain-at9.0-runtime-at8.0-compat-9.0-2.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/at9.0/share/zoneinfo to /opt/at9.0/etc/localtime
- advance-toolchain-at9.0-runtime-compat-9.0-2: DO NOT INSTALL it on RHEL7 and beyond. These are intended for runtime compatibility on RHEL6 only (see below).
Installation for runtime compatibility on previous distribution versions
Users running applications on previous distributions of SLES or RHEL may install the compatibility rpm advance-toolchain-at9.0-runtime-compat-9.0-2 in order to get the Advance Toolchain runtime libraries.
Installation of the cross-compiler (Intel x86)
You can download advance-toolchain-at9.0-cross-9.0-2 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.
