I'm configuring OPENLDAP 2.4.35. on Redhat Linux, I have already installed Berkley DB 4.8.30 as a prerequisite. I also checked the version compatibility from OPENLDAP's README file, which says: SLAPD: BDB and HDB backends require Oracle Berkeley DB 4.4 - 4.8, or 5.0 - 5.1. It is highly recommended to apply the patches from Oracle for a given release. Still I'm getting this error: checking db.h usability... yes checking db.h presence... yes checking for db.h... yes checking for Berkeley DB major version in db.h... 4 checking for Berkeley DB minor version in db.h... 8 checking if Berkeley DB

I noticed rpmbuild (-bb and --buildroot options) creates the .rpm in different locations depending of what OS are you using: GNU/Linux Ubuntu <= 9.04: /usr/src/rpm/... GNU/Linux Ubuntu >= 9.10: /home/rpmbuild/... GNU/Linux Fedora: /usr/src/redhat/... So how can I set manually the destination folder for all OS? Replying myself, adding: %define _rpmdir /outputdir to .spec file. You may want to use the command argument --define : For example, this will send the rpm files into the current directory. rpmbuild anything.spec --bb --define "_rpmdir $(pwd)" This will send the rpmsto output dir rpmbuild

Code Here is the program that gives the segfault. #include <iostream> #include <vector> #include <memory> int main() { std::cout << "Hello World" << std::endl; std::vector<std::shared_ptr<int>> y {}; std::cout << "Hello World" << std::endl; } Of course, there is absolutely nothing wrong in the program itself. The root cause of the segfault depends on the environment in which its built and ran. Background We, at Amazon, use a build system which builds and deploys the binaries ( lib and bin ) in an almost machine independent way. For our case, that basically means it deploys the executable
