Control: tags -1 help Hi all,
The undefined reference to those functions, means that there is a problem in linking with libminimap2 which implements them. Those functions are implemented in map.c of that library. I am able to reproduce the bug with pbuilder (sid) on the buster. I made some investigations: The size of the latest snapshot of libminimap2-dev package is far smaller than its predecessors which could be found in [1]. The latest snapshot (dfsg-7) is around 23 KB, but its direct predecessor (dfsg-6) is 1.4 MB. I extracted 2 latest snapshots and examined the contents of libminimap2.a and specially map.o which should define those functions. I run the `nm --demangle map.o` and the result is: On the latest snapshot (dfsg-7): nm: map.o: no symbols On its predecessor (dfsg-6): U __assert_fail U cputime U fclose U kfree U kmalloc U km_destroy U km_init U km_stat 00000000 T ks_heapdown_heap 00000000 T ks_heapmake_heap 00000000 T ks_ksmall_heap U kt_for U kt_pipeline U mm_align_skeleton U mm_bseq_close U mm_bseq_open U mm_bseq_read3 U mm_bseq_read_frag2 U mm_chain_dp U mm_dbg_flag U mm_err_fread U mm_err_fwrite U mm_err_puts U mm_est_err U mm_gen_regs U mm_hit_sort U mm_idx_destroy U mm_idx_get U mm_join_long 00000000 T mm_map 00000000 T mm_map_file 00000000 T mm_map_file_frag 00000000 T mm_map_frag U mm_pair U mm_realtime0 U mm_seg_free U mm_seg_gen U mm_select_sub U mm_select_sub_multi U mm_set_mapq U mm_set_parent U mm_set_sam_pri U mm_sketch U mm_split_init 00000000 T mm_split_merge U mm_split_merge_prep U mm_split_rm_tmp 00000000 T mm_tbuf_destroy 00000000 T mm_tbuf_get_km 00000000 T mm_tbuf_init U mm_verbose U mm_write_paf3 U mm_write_sam3 U radix_sort_128x U realtime U sdust_buf_destroy U sdust_buf_init U sdust_core U seq_comp_table U stderr We see that dfsg-6 exports required functions, but dfsg-7 not! Thus I concluded that there is a problem with the dfsg-7 build. So I downloaded the dfsg-7 source code and built it with pbuilder (sid) and the built package was the same 23 KB size and the problem was the same (no function is exported). Then I downloaded dfsg-6 source and built it with pbuilder (sid) and WOW! The size became 23 KB, while the snapshot size is 1.4MB on [1]! And now the functions are not exported while were exported on the snapshot on [1]. Then I built both sources (dfsg-6 and dfsg-7) on buster with debuild successfully and both have the size 1.4MB and both contents are OK and export required function symbols. The conclusion: IMHO the problem is with the build tool-chain which results in such a difference in the size of the built package, in comparison with previous snapshots from the same source, which does not provide required functions in the built minimap2 library. But I may have missed something. So I would like to ask kindly for any suggestion which may provide a better resolution to the bug. Please CC me in any response since I am not subscribed to the list.
