Segmentation core dump when running mt_prep_snap #3

Closed bjmarfito closed 2 years ago

bjmarfito commented 2 years ago

Hi @DinhHoTongMinh, I have just stacked Sentinel-1 SLC images using Snap. However, I encountered the error "segmentation fault (core dumped)" while running the mt_prep_snap to be able to generate files that can be ingested into TomoSAR. Could you help me fix this issue?

Below are the details of the error.

Hi @bjmarfito, This is due to a compiled error. It can be solved by Installing g++-7 and gcc-7 (just incase, to make sure both are present) Changing the compiler from CC = g++ to CC = g++-7 in the StaMPS_master/src/Makefile cd StaMPS_master/src make make install

After stamps_export, please run TomoSAR. You then can run 'mt_prep_snap_psds' or 'mt_prep_snap_comp'. Please have a look in 'https://github.com/DinhHoTongMinh/TomoSAR/blob/main/PSDS_ComSAR_README.md'

It worked as you have suggested. Thank you @DinhHoTongMinh!
