window系统下的库分析命令

.a是静态库归档，先看成员文件，再看符号最有效。$lib = 'D:\demo\libs\libhttp.a'列出库内有哪些.o成员：ar t $libPS D:\demo ar t $libum_http.c.obj这里.obj就是.o文件查看全部符号：nm -C $lib只看该库实际定义并导出的全局符号：nm -C -g --defined-only $libPS D:\demo nm -C -g --defined-only $libum_http.c.obj:00000000 T dns_resolve_cb_register00000004 B ip_addr_get_func00000000 T um_httpclient_chunk_set00000000 T um_httpclient_cid_set00000000 T um_httpclient_config_set00000000 T um_httpclient_conn_timeout_set00000000 T um_httpclient_connect00000000 T um_httpclient_create00000000 T um_httpclient_custom_header_free00000000 T um_httpclient_custom_header_get00000000 T um_httpclient_custom_header_set00000000 T um_httpclient_delete00000000 T um_httpclient_get_response_code00000000 T um_httpclient_get_status00000000 T um_httpclient_parse_header00000000 T um_httpclient_request_content_free00000000 T um_httpclient_request_content_get00000000 T um_httpclient_request_content_send00000000 T um_httpclient_request_start00000000 T um_httpclient_rsp_timeout_set00000000 T um_httpclient_specific_header_free00000000 T um_httpclient_specific_header_get00000000 T um_httpclient_specific_header_set00000000 T um_httpclient_ssl_set00000000 T um_httpclient_terminate00000000 T um_httpclient_uri_encode00000000 T um_httpclient_url_parse查 ssl相关符号，比如函数名等：nm -C $lib | Select-String 'ssl'PS D:\demo nm -C $lib | Select-String 'ssl' 00000000 T um_httpclient_ssl_set查看某个成员或库的符号表、段信息：objdump -t $lib objdump -h $libPS D:\demo objdump -t $lib | moreIn archive D:\demo\libs\libhttp.a:um_http.c.obj: file format elf32-little00000000 l df *ABS* 00000000 um_http.c00000000 l d .text 00000000 .text00000000 l d .data 00000000 .data00000000 l d .bss 00000000 .bss00000000 l d .text.um_httpclient_create 00000000 .text.um_httpclient_create00000000 l .text.um_httpclient_create 00000000 .L000000000 l .text.um_httpclient_create 00000000 $xrv32i2p0_m2p0_c2p0_zmmul1p0_xlinxma1p0_xlinxmb1p0_xlinxmc1p000000000 l .text.um_httpclient_create 00000000 .L00000000c l .text.um_httpclient_create 00000000 .L000000000 l O .sbss 00000004 g_client_ops_mutex00000012 l .text.um_httpclient_create 00000000 .L000000000 l F .text.init_http_global_mutex 00000056 init_http_global_mutex00000020 l .text.um_httpclient_create 00000000 .L0...PS D:\demo objdump -h $lib | moreIn archive D:\demo\libs\libhttp.a:um_http.c.obj: file format elf32-littleSections:Idx Name Size VMA LMA File off Algn 0 .text 00000000 00000000 00000000 00000034 2**1 CONTENTS, ALLOC, LOAD, READONLY, CODE 1 .data 00000000 00000000 00000000 00000034 2**0 CONTENTS, ALLOC, LOAD, DATA 2 .bss 00000000 00000000 00000000 00000034 2**0
