- Subject: [PATCH] cmds/records: replace ADDR_NO_RANDOMIZE by its value
- uClibc-ng lacks the definition of ADDR_NO_RANDOMIZE, causing a build
- failure. A patch was submitted to upstream uClibc-ng to address this
- issue, but in the mean time, use an hardcoded value.
- Using a #ifdef ... #endif test doesn't work as this value is defined
- through an enum in glibc.
- Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
- Upstream: https://github.com/namhyung/uftrace/pull/1389
