Error when trying to build

[t3chn0m4g3]

When I try to build honeytrap in Debian Buster I get the following error ...

Any ideas?

UPDATE: Builds without problem in Debian Stretch.

Hey Marcus,

htm_ftpDownload.c:81:2: error: 'strncpy' output truncated before terminating nul copying 7 bytes from a string of the same length [-Werror=stringop-truncation] strncpy(full_name, "plugin-", 7); ^~~~~~~~ htm_ftpDownload.c:82:2: error: 'strncpy' output truncated before terminating nul copying 11 bytes from a string of the same length [-Werror=stringop-truncation] strncpy(&full_name[7], module_name, 256 < strlen(module_name) ? 256 : strlen(module_name)); ^~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[4]: *** [Makefile:681: htm_ftpDownload.lo] Your compiler complains about the fact that strncpy() does not copy any null bytes. The two instances are fine, though.

Try the attached patch or edit src/modules/Makefile.am and add -Wno-stringop-truncation to AM_CFLAGS.

Let me know if this helps.

Hi Tillmann,

thanks for the explanation and the swift feedback 😄 Github seems to have blocked the attachment, no patch here.

However, based on your info I managed to build it, once adding -Werror -Wno-stringop-truncation -Wno-stringop-overflow to both the Makefile.am in src and src/modules.

Without -Wno-stringop-overflow I run into ...

/bin/bash ../../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I../..  -I../  -Wall -Werror -Wno-stringop-truncation -g -O2 -c -o htm_tftpDownload.lo htm_tftpDownload.c

htm_tftpDownload.c: In function 'get_tftp_resource':
htm_tftpDownload.c:218:2: error: 'strncpy' specified bound depends on the length of the source argument [-Werror=stringop-overflow=]
  strncpy(tftp_command+2, save_file, strlen(save_file));

Thanks for your help, appreciate if you could apply the patch.

Best regards, Marco.
