Hi, Still struggling with this issue, To summarize the steps that I took to see the mongodb segfault issue,
Here are the steps I took, Download poky (gatesgarth) git clone https://git.yoctoproject.org/git/poky -b gatesgarth openembedded (gatesgarth) git clone https://github.com/openembedded/meta-openembedded.git -b gatesgarth Add meta-oe layers to bblayers Add mongodb to IMAGE_INSTALL Build and runqemu core-image-minimal using qemuarm64 After just these steps I am seeing segfault. Anyone know about this issue/what could possibly be the issue? If not, would also appreciate any pointers on debugging this issues, For debugging: Added the following to local.conf, (referenced this: https://developer.ridgerun.com/wiki/index.php?title=Preparing_Yocto_Development_Environment_for_Debugging) IMAGE_INSTALL_append = " mongodb mongodb-dbg" EXTRA_IMAGE_FEATURES += " tools-debug" PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory' #Specifies to build packages with debugging information DEBUG_BUILD = "1" # Do not remove debug symbols INHIBIT_PACKAGE_STRIP = "1" # OPTIONAL: Do not split debug symbols in a separate file INHIBIT_PACKAGE_DEBUG_SPLIT= "1" Then using gdb on mongod, I get: Reading symbols from mongod... (No debugging symbols found in mongod) Noticed nothing is in the -dbg pkgs of mongod, (without “PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'”, debug files are here: /usr/bin/.debug/mongod, but /usr/bin/.debug/mongod.debug is where gdb is expecting it, if I copy it as such I get the CRC mismatch issue below) Removed the following from the local.conf and added the following to mongod recipe: + 120 INHIBIT_PACKAGE_STRIP = "1" + 121 INHIBIT_PACKAGE_DEBUG_STRIP = "1" + 122 DEBUG_BUILD = "1" Now I see under mongodb-dbg: usr/lib/debug/usr/bin/mongod.debug but when running gdb I see warning: the debug information found in "/usr/lib/debug//usr/bin/mongod.debug" does not match "/usr/bin/mongod" (CRC mismatch). (No debugging symbols found in mongod) Tried the same experiment in zeus, I get, Reading symbols from mongod... Reading symbols from /usr/bin/.debug/mongod... BFD: error: /usr/bin/.debug/mongod(.debug_info) is too large (0x4d617681 bytes) warning: Can't read data for section '.debug_info' in file '/usr/bin/.debug/mongod' (No debugging symbols found in /usr/bin/.debug/mongod) Am I missing something here? Any pointers would be much appreciated!

Not a perfect test by any means but also tried mongodb version from zeus release where it was working and same issue. hoping to maybe get some pointers in the right direction to pinpoint issue, also having some trouble setting up debug environment correctly, Keep getting either ‘no debug symbols found’ or, ‘the debug info found in /usr/bin/.debug/mongod.debug does not match /usr/bin/mongod (CRC mismatch)’ With what I think are all the correct flags setup to debug.. INHIBIT_PACKAGE_STRIP = "1" INHIBIT_PACKAGE_DEBUG_STRIP = "1" INHIBIT_SYSROOT_STRIP = "1" DEBUG_BUILD = "1" PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory' Adding mongodb-dbg, adding tools-debug Any pointers would be much appreciated! Thanks, Jaewon
